Kim Du-han quotes:

Losing a family member, and her dying knowing she didn't have to die, that...is a scar that will last forever for the people remaining, and even with good actions and good words, that scar will never disappear. Ever.

Lots of people misunderstand this. They think not experiencing fear means they're courageous. Bravery isn't about not being afraid, it's about persevering despite your fears.

Do you know what is really embarrassing and makes your pride hurt? Lacking some skill? Not being able to earn some money? It's not that. Fearing something once, and being scared of it forever.

Forgiveness depends on the person. If he's saying sorry to make himself comfortable, then don't forgive him. If he's asking for forgiveness sincerely, then it's okay to forgive him. If you don't know what's on that person's mind... It's easy. Watch carefully how that person has lived up to now, and how he's living right now.

A doctor is not a religious man. You should never give people vague hope or possibility.

I know how sad it is when you won't be able to realize your dream. But do you know what's great about dreams? You can always have a different dream. Just like the way you dream every night in your sleep, you can just dream another dream. You're not throwing your dream away, but having a different dream.
