Great execution towards a terrible idea will get you nowhere.

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

As you grow, the productivity I think, goes down with the square of the number of employees if you don't make an effort.

A related advantage of mission oriented ideas, is that you yourself will be dedicated to them.

You certainly don't need to have everything figured out in the path from here to world domination.

The best source by far for hiring is people that you already know and people that other employees in the company already know.

Cofounder relationships are among the most important in the entire company.
