Great companies with the way they work, first start with great leaders.

This is all about having great leaders who can drive agile innovation and agile decision-making.

I like to tell people that all of our products and business will go through three phases. There's vision, patience, and execution.

I think there are lots of opportunities to improve the product. When you read the press, people say, "Oh, the product needs improvement." I look at that and say, "Hey, that's an exciting thing to get behind!" Because they can improve that product. That leaves more upside from an innovation and revenue potential than you're gonna find in a lot of places. So you could say that's a downside, I see that as an opportunity.

Linux is a cancer that attaches itself in an intellectual property sense to everything it touches.

If you look at companies with upside potential, Twitter's right there. They've established a brand in a world where it's extremely difficult to establish a brand. It's a global brand, people recognize it, people want to let you know what their Twitter handles are, etc.

You get some success. You run into some walls...it's how tenacious you are, how irrepressible, how ultimately optimistic and tenacious you are about it that will determine your success.
