David McRaney quotes:

The more pessimistic your explanatory style, the easier it is to slip into learned helplessness."

If you neglect your personal space and allow chaos and clutter to creep in, it will affect you, and perhaps encourage further neglect. Positive feedback loops should improve your life, not detract from it. You can't prime yourself directly, but you can create environments conducive to the mental states you wish to achieve.

If you fail to believe you will procrastinate or become idealustic about how awesome you are at working hard and managing your time, you never develop a strategy for outmaneuvering your own weakness.
