We talk to a team they've gotten new things done, that's the best predictor we have that a company will be successful.

I myself used to believe ideas didn't matter that much, but I'm very sure that's wrong now.

You can't be focussed without really great communication

You need to figure out what the 2 or 3 most important things are, and then just do those.

Don't let the company get distracted or excited about other things. A common mistake is that companies get excited by their own PR.

In general, it's best if you're building something that you yourself need.

You should always know how you're doing against your metrics. You should always have a weekly review meeting every week.
