I create offbeat advice; I don't follow it. I rarely take third-party advice on my investments.

Treat your customers like they own you. Because they do.

Tech stocks were the cubic zirconium of the market. They looked good and were sexy, but they just were a way for the company selling them to make money. That's always going to be transient in terms of the stock market. What's real is that companies have to compete. Technology used well is a great tool to enable that if only because most companies dont use technologies well.

The one thing in life you can control is your effort. Are there any shortcuts in the beauty business? No. That was the first lesson I learned. You can't just rocket to the top.

Never follow your dreams. Follow your effort. It's not about what you can dream of. That's easy. It's about whether or not it's important enough to you to do the work to be ready to be successful in that business.

On the Internet, there are an unlimited number of competitors. Anybody with a Flip camera is your competition. What makes it even worse is that YouTube is willing to subsidize the cost of your bandwidth. So anybody can create and distribute for free basically, but the real cost is marketing. And that's always the big cost - how do you stand out and what's the cost of standing out? And there's no limit to that cost.

Having the ability to be brutally honest with yourself is the greatest challenge you face when creating a business model. Too often we oversell ourselves on the quality of the idea, service, or product. We don't provide an honest assessment of how we fit in the market, why customers will buy from us, and at what price.
