You should be giving out a lot of equity to your employees.

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

AirBnB spent 5 months interviewing their first employee, before they hired someone and in their first year, they only hired 2 people.

You should always know how you're doing against your metrics. You should always have a weekly review meeting every week.

Most good founders that I know at any given time have a set of small overarching goals for the company that everybody in the company knows.

Remember that the idea will expand, and become more ambitious as you go.

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