Most years, if you were to ask me how much I make, the genuine answer is that I have no clue. I usually find out the answer to that question once a year, at tax time, when my accountant tells me.

I try to find, celebrate and teach leaders how to build platforms that will inspire others.

Sometimes spending time with someone who is perceived as 'successful' can make us feel less successful.

I find, when you're an optimist, life has a funny way of looking after you.

You can't the answer if you don't know the question.

Wal-Mart's size and scale is so vast they literally have the ability to change the face of the entire country. If Wal-Mart were to make a decision tomorrow to refuse to sell a single product made with partially hydrogenated oils, for example, we'd probably see rates from heart disease decline a few years later. That's how powerful Wal-Mart is.
