Here's a good rule of thumb: don't worry about a competitor at all, until they're actually beating you with a real shipped product.

By the way, that's my number one piece of advice if you're going to join a startup: pick a rocket ship.

Two other things that we hear again and again from our founders, they wish they had done earlier, and that is... simply writing down how you do things and why you do things.

It takes years and years, usually a decade, to create a great startup.

You need to have a culture where people have very high quality standards in everything the company does, but still move quickly.

Everyone starting a startup for the first time is scared, and everyone feels like a bit of an imposter.

You really want to know your cofounders for a while, ideally years.
