Most of the best hires that I've made in my entire life have never done that thing before.

Before 20 or 25 employees, most companies are structured with everyone reporting to the founder. It's totally flat.

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.

Great execution towards a terrible idea will get you nowhere.

Because so few people make an actual long term commitment to what they're building, the ones that do have a huge advantage.

So you should always stay on top of people's vesting schedules.

You can have a startup and one other thing, you can have a family, but you probably can't have many other things.
