If you really want to be world class - to be the best you can be - it comes down to preparation and practice.
It's amazing how far you will get by just staying with something long enough. Most people give up too early.
The fears you run from run to you.
Spend time doing things that matter.
Love what you have. And then go for what you want.
First of all, begin to live out of the glory of your imagination, not your memory.
