Sara Blakely quotes:

My dad encouraged us to fail. Growing up, he would ask us what we failed at that week. If we didn't have something, he would be disappointed. It changed my mindset at an early age that failure is not the outcome, failure is not trying. Don't be afraid to fail.

I think failure is nothing more than life's way of nudging you that you are off course. My attitude to failure is not attached to outcome, but in not trying. It is liberating. Most people attach failure to something not working out or how people perceive you. This way, it is about answering to yourself.

I shopped for body shapers for the first time in my life and I was horrified. They were thick - it was like wearing workout clothes and they all had a leg band on one side that showed through the pants.

Don't solicit feedback on your product, idea or your business just for validation purposes. You want to tell the people who can help move your idea forward, but if you're just looking to your friend, co-worker, husband or wife for validation, be careful. It can stop a lot of multimillion-dollar ideas in their tracks in the beginning.

I'd get kicked out of buildings all day long, people would rip up my business card in my face. It's a humbling business to be in. But I knew I could sell and I knew I wanted to sell something I had created. I cut the feet out of those pantyhose and I knew I was on to something. This was it.

My husband is such a healthy eater. Except when it comes to sweets. He never consumes anything except fruit until noon. And then from noon on he might have some brown rice and some tofu, and then, come eight or nine at night, he orders three mud-pie double-chocolate pieces of cake and eats all three of them.

I'll mix a lot of things. I'll wear a Temperley dress with flip flops, or I might be in head-to-toe Gucci and have on a ring that I got from a gumball machine for 50 cents.

Don't let what you don't know scare you, because it can become your greatest asset. And if you do things without knowing how they have always been done, you're guaranteed to do them differently.

My training of cold-calling and everyone under the sun telling me no, and my keeping going, was a huge part of the first two years of Spanx.

Where I get my energy is: 'How can I make it better?'

Eminem's 'Lose Yourself' is my go-to song to pump myself up if I'm having a tough time or if I get really nervous right before a speech.

I started thinking about joy. Everything in our society is so purposeful. Let's bring joy back to the experience.

I've always leaned toward a feminine, funky style, even in business settings. I used to paint my nails blue in 1993, before it was mainstream.

It's really a full-time job to manage our lives.

When I cut the feet out of my pantyhose that one time, I saw it as my sign. I had been visualizing being self employed prior to this happening. It was my mental preparation meeting the opportunity in that moment.

I couldn't figure out what to wear under my clothes. The body shapers were too thick at the time.

If we can put a man on the moon, we can make pantyhose comfortable.

Most of us want to tell our coworkers or friends, or husbands or wives, our ideas. For what reason? We want validation. But I feel ideas are most vulnerable in their infancy. Out of love and concern, friends and family give all the reasons or objections on why [you] shouldn't do it. I didn't want to risk that.

I didn't want women to walk out of the dressing rooms feeling depressed and wanting a cocktail.

When I'm bored or tired of being blonde, I'll throw on a wig. It's a lot less of a permanent way to change your look, and I have about 10 - all different colors, shapes, bobs, long hair, short, feathered.

I failed the LSAT. Basically, if I had not failed, I'd have been a lawyer and there would be no Spanx. I think failure is nothing more than life's way of nudging you that you are off course. My attitude to failure is not attached to outcome, but in not trying. It is liberating.

I think my story says that, when women are given the chance and the opportunity, that we can achieve a lot. We deliver.

Everything in our society is so purposeful.

I aim to be pretty - I gave up dressing to be sexy in the eighties.

I took a Fear of Flying class, and I always missed the class, because I was always flying.

My revenue was $4 million my first year in business, off of one $20 item.

My first account was Neiman Marcus. I cold-called them just like I had cold-called businesses when I was selling fax machines for seven years.

I grew up in a house where my father encouraged my brother and me to fail. I specifically remember coming home and saying, 'Dad, Dad, I tried out for this or that and I was horrible,' and he would high-five me and say, 'Way to go.'

I have this system where if I buy three or four new things, I give away three or four things. Sometimes, it's a very painful system, but shopping is even better when you know that someone else who needs it will be getting. Keep the clothing karma going, I say.

Shapewear is the canvas and the clothes are the art.

Everything about my journey to get Spanx off the ground entailed me having to be a salesperson - from going to the hosiery mills to get a prototype made to calling Saks Fifth Avenue and Neiman Marcus. I had to position myself to get five minutes in the door with buyers.

Don't be intimidated by what you don't know.

My saddlebags are why Spanx exist! Now that I have a baby I also have a muffin top.

I made a conscious decision not to tell anyone in my life. Now I tell people - don't tell anyone your idea until you have invested enough of yourself in it that you are not going to turn back. When a person has an idea at that conception moment it is the most vulnerable - one negative comment could knock you off course.

Within the first year of launching my company, Spanx, I decided to go over to England and cold-call Harrods, Harvey Nichols, and Selfridges the same way I had cold-called Neiman Marcus, Saks, Nordstrom, and Bloomingdale's here in the United States.

I pledge to invest in women because I believe it offers one of the greatest returns on investment. I am committed to the belief that we would all be in a much better place if half the human race (women) were empowered to prosper, invent, be educated, start their own businesses, run for office essentially be given the chance to soar.

I cut the feet off of a pair of panty hose and it allowed me to wear a pair of great strappy sandals. I didn't see lines but the hose rolled up at my feet - and that's how Spanx born.

In the next decade, I see Spanx going worldwide. Everywhere. No butt left behind. It's going to be all over the world and it's going to be an aspirational brand that transcends categories. There's so many things we can improve upon and make better.

The word 'Spanx' was funny. It made people laugh. No one ever forgot it.

I got a call from the Oprah Winfrey Show. Oprah had chosen Spanx as one of her favorite products in 2000. I had boxes of product in my apartment and I had two weeks notice that she was going to say she loved it on TV and I had no shipping department.

I always joke and say I want to invent a comfortable stiletto and then retire.

Failures are life's way of nudging you and letting you know you are off course. Trying new things and not being afraid to fail along the way are more important than what you learn in school.

I'd never worked in fashion or retail. I just needed an undergarment that didn't exist.

Having a mental snapshot of where you are, where you are going, and what you are moving toward is incredibly powerful.

I cut the feet out of my control top pantyhose to wear under these white pants and that was the ah-ha moment that started Spanx. My own butt was my own inspiration!

I cut the feet out of control top pantyhose one night, threw them on under my white pants and realized that the toning and shaping was perfect and that the hosiery material is thin enough that I could make shape wear out of it.

When I was 7, I came up with the idea of 'charm socks.' My mom would take me to buy bags of plastic charms, we would sew them on frilly white socks, and I sold them at school.

The thing about fashion - it's like ducks going quack, quack quack. It's being dictated from above, and it just makes me want to rebel against it.

What I most identify with is effortless fashion, looking as if someone's not put a lot of effort into their look.

I've always had that gratitude that I had the opportunity to pursue my potential. So I think my story says that, when women are given the chance and the opportunity, that we can achieve a lot. We deliver. We can make the world a better place, one butt at a time.

It's important to be willing to make mistakes. The worst thing that can happen is you become memorable.

Courage is doing something despite the fear, and I've worked hard on being a courageous person.

Ensure that you do things differently from everyone else

Every time I went on stage I was so terrified I almost threw up.

Failure is not attached to outcome, but in not trying. This way, it is about answering to yourself.

Failure is not the outcome - failure is not trying. Don't be afraid to fail.

Failure to me became not trying versus not succeeding

I did not like the way I looked in a pair of white pants.

I didn't like the way it looked in white trousers, and I couldn't find anything to work underneath them.

I knew that I wanted to start my own business. I knew that I wanted to work for myself. I was no stranger to the word no. You just have to keep going.

I think very early on in life we all learn what we're good at and what we're not good at, and we stay where it's safe.

Ideas, even million-dollar ones, are most vulnerable in their infancy; don't share them with too many people. However, don't hide your plan from people who can help you move it forward.

If somebody can do something 80 percent as good as you think you would have done it yourself, then you've got to let it go.

Instead of failure being the outcome, failure became not trying. And it forced me at a young age to want to push myself so much further out of my comfort zone.

Money is fun to make, fun to spend and fun to give away.

The smartest thing I ever did was to hire my weakness.

The thought of my mortality - I think about it a lot. I find it motivating. It can be any time that your number's up.

We don't have the luxury of time. We spend more because of how we live, but it's important to be with our family and friends.

What you don't know can be your greatest asset

Whatever you can think, you can create; just have a very clear vision... Once you have your snapshot, work on filling in the blanks to get to that place.

When I was a child, my father used to encourage my brother and me to fail. At the dinner table, instead of asking about the best part of our day, he would ask us what we failed at that week. If we didn't have something to tell him, he would be disappointed. When we shared whatever failure we'd endured, he'd high-five us and say, 'Way to go!' The gift my father gave us by doing this was redefining what failure truly meant.

When I was growing up, my dad would encourage my brother and I to fail. We would be sitting at the dinner table and he would ask, 'So what did you guys fail at this week?' If we didn't have something to contribute, he would be disappointed. When I did fail at something, he'd high-five me. What I didn't realize at the time was that he was completely reframing my definition of failure at a young age. To me, failure means not trying; failure isn't the outcome. If I have to look at myself in the mirror and say, 'I didn't try that because I was scared,' that is failure.

When something I can't control happens, I ask myself : where is the hidden gift, where is the positive in this?

Where I get my energy is: 'How can I make it better?
