It's better to have no cofounder than to have a bad cofounder, but it's still bad to be a solo founder.

To get the very best people- they have a lot of great options, and so it can easily take a year to recruit someone.

Execution gets divided into two key questions: 1) can you figure out what to do and 2) can you get it done.

Remember that you are more likely to die because you execute badly than get crushed by a competitor.

Mediocre founders spend a lot of time talking about grand plans, but they never quite make a decision.

If you look at successful pivots, they almost always are a pivot into something that the founder wanted. Not a random made up idea.

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