If someone is getting every decision wrong, that's when you need to act, and at that point it'll be painfully aware to everyone.

Mediocre founders spend a lot of time talking about grand plans, but they never quite make a decision.

In general don't start a startup you're not willing to work on for ten years.

You also want to fire people who a) create office politics, and b) who are persistently negative.

One thing that founders always underestimate is how hard it is to recruit.

Most startups are not nearly focussed enough. They work hard...maybe, but they don't work hard on the right things.

... but actually it sucks to have a lot of employees, and you should be proud of how few employees you have.
