If you can just learn to think about the market first, you will have a big leg up on most people starting startups.

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

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

Most startups are not nearly focussed enough. They work hard...maybe, but they don't work hard on the right things.

Startups are very hard no matter what you do; you may as well go after a big opportunity.

A single mediocre hire in the first five will often in fact kill a startup.

One thing that often disrupts momentum and really shouldn't is competitors.
