Every thing at a startup gets modeled after the founders. Whatever the founders do becomes the culture.

Someday, you need to build a business that's difficult to replicate. This is an important part of a good idea.

For early employees you want people that have somewhat of a risk-taking attitude.

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

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

Execution gets divided into two key questions: 1) can you figure out what to do and 2) can you get it done.

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