Wealth really is a never-ending process. So is running money. You can't just walk away and ask about the meaning of life. - Andy Kessler

A product lowers the cost of doing something and eventually, customers will figure this out and buy the stuff in big volume, but they're not going to buy yet. You've got to have real conviction to step up and own this kind of company-you're staring over the edge of the waterfall, not sure when the growth is going to start.

Give me a big enough sandbox to play in, and I'll find the part of it not being used as kitty litter.

I've been doing this for years. Never invest in a company with the target price for the stock in the name of the company.
