The idea should come first, the startup should come second.

In the early days of a startup, people's compensation is whatever you negotiate with a founder and it's all over the place.

There's at least a hundred times more people with great ideas than people that are willing to put in the effort to execute them well.

At the beginning, you should only hire when you have a desperate need to.

A lot of people treat choosing their cofounder with even less importance than they put on hiring. Don't do this.
