I've been good at product entrepreneuring.

The first rule (of investing) for me is don't have rules. You find one amazing investment and that's all that matters. If you pick the right body of water, you might not need a boat.

You're not smarter than your competitor. Just copy what they do and do it until you get their numbers.

Don't lose sight of user delight.

I think you're defined as a company by what you choose to do and what you choose not to do.

There are people who want the comfort and structure of a job where they're given tasks and told what to do. I think it's actually a minority of people. The majority of people don't want that, but I'd say that the companies I've built are full of people with something to prove.

Get five or six of your smartest friends in a room and ask them to rate your idea.
