Be so good at what you do that no one else in the world can do what you do.
Change is hardest at the beginning, messiest in the middle and best at the end.
Your environment (your home, your office, the magazines you read etc.) dramatically affects your levels of achievement
On the other side of the fear live your possibilities.
Never get into the petty habit of measuring yourself worth against other people's net worth.
If you really want to be world class - to be the best you can be - it comes down to preparation and practice.
