I'm always striving to be better at what I do. Erik Barker's article (click on the surfer to get to it) provides a good synopsis:
10,000 hour rule - in other words, getting good at something and working hard at it for a long period of time pays off!
Genetics - you'll be more inclined and better at certain things. Focus on the things you start or begin to be naturally good at.
A Great Team - yes absolutely, build a team of like minded, hard working, ambitious and smart people.
Be a Giver - give when you can all the time.
Combine everything and you've got a winner!
