I like Dr. Daniel Amen's 18/40/60 Rule: When you're 18, you worry about what everybody is thinking of you; when you're 40, you don't give a darn what anybody thinks of you; when you're 60, you realize nobody's been thinking about you at all.

One of the things I tell people in my seminars is to hang out with positive, nurturing people. You become like who you hang out with.

There are essentially two things that will make you wise -- the books you read and the people you meet.

If you hang in there long enough, you will eventually reach your goal.

If you go to a tree with an ax and take five whacks at the tree every day, it doesn't matter if it's an oak or a redwood; eventually the tree has to fall down.

Decide what it is you want, write it down, review it constantly, and each day do something that moves you toward those goals.

I generally find that comparison is the fast track to unhappiness. No one ever compares themselves to someone else and comes out even. Nine times out of ten, we compare ourselves to people who are somehow better than us and end up feeling more inadequate.
