Take what you do seriously, but yourself lightly
Business is like tennis. Those who serve well win.
Your game is only as good as your practice.
I grew up in New England. I think I was brought up with the Puritan ethic: that if you worked really hard in life, then good would come to you. The harder you work, the luckier you get. I've come to believe that it's the smarter you work, the better.
Don't wait until people do things exactly right before you praise them.
Do your best to succeed and push the limits without violating them.
