Positive thinking will let you do everything better than negative thinking will.
A Muslim fanatic and a Christian fanatic, a Jewish fanatic, a secular fanatic, an atheist fanatic, a communist fanatic - all of them are the same. The thinking that, 'If you don't think like me, that if you are not with me, then you are against me;' this is something to condemn.
Don't think. Thinking is the enemy of creativity. It's self-conscious, and anything self-conscious is lousy. You can't try to do things. You simply must do things.
I used to do my best thinking while staring out airplane windows. The seat-back video system put a stop to that. Now I sit and watch old' Friends' and 'Everybody Loves Raymond' episodes. Walking is good, but here again, technology has interfered. I like to listen to iTunes while I walk home. I guess I don't think anymore.
The problem is that at a lot of big companies, process becomes a substitute for thinking. You're encouraged to behave like a little gear in a complex machine. Frankly, it allows you to keep people who aren't that smart, who aren't that creative.
