When I meet successful people I ask 100 questions as to what they attribute their success to. It is usually the same: persistence, hard work and hiring good people.
I have my parents to thank for that, they raised me to be active and play all sports. They taught me the importance of staying healthy, being focused and setting goals in whatever I do.
Balance is key: I need to be successful in my career to feel fulfilled, be surrounded by people I care about to share it with, and have my health to be able to do the things I love to do!
