Even though plans themselves are worthless, the exercise of planning is very valuable and totally missing in most startups today.

You can't be focussed without really great communication

You want to sound crazy, but you want to actually be right.

You should think about for the next 10 years, you're going to be giving out 3-5% of the company every year.

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

You only get points when you make something the market wants. So if you work really hard on the wrong things, no one will care.

You want to continue to be run by great products, not process for it's own sake.
