Profitability and sustainability are not opposites - they're two sides of the same coin.

Successful people maintain a positive focus in life no matter what is going on around them. They stay focused on their past successes rather than their past failures, and on the next action steps they need to take to get them closer to the fulfillment of their goals rather than all the other distractions that life presents to them.

I'm interested in the edges of things, where they meet and overlap.

I'm a black American, I am proud of my race. I am proud of who I am. I have a lot of pride and dignity.

人们永远不会注意到已经做了什么；人们只能看到还有待完成的事情。
