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

Remember that you are more likely to die because you execute badly than get crushed by a competitor.

One of the keys to focus, and why I said cofounders that aren't friends really struggle, is that you can't be focused without good communication.

If you pivot, do it fully and with conviction. The worst thing is to try to do a bit of the old and the new-it's hard to kill your babies.

It's become popular in recent years to say that the idea doesn't matter.

Or a way to stay on strangers couches, that just sounds terrible all around.

You don't get to make their decisions but you do get to choose the decision makers.
