Probably the most significant thing I have learned in life is that you can't change your actions by changing your thinking, and that is because you can't change your thinking by just thinking or with a magic pill. You have to change your thinking by changing your actions.
You can solve a lot of bad thinking this way. If you have poisonous thinking, change the way you behave and the thoughts will follow.
It is the hardest thing you will ever do, but it really works.
This works in reverse, too. And I truly believe Bush acted like a retard for so long that his thinking became retarded. A snake swallowing its own tail.
Seriously. Not kidding.
