If someone is difficult to talk to, if someone cannot communicate clearly, it's a real problem in terms of their likelihood to work out.

More important than starting any startup, is getting to know a lot of potential co-founders.

Unfortunately the trick to great execution is to say no a lot.

The way to have a company that executes well is you have to execute well yourself.

The cost of getting an early hire wrong is really high.

There are exceptions of course, but most companies start with a great idea - not a pivot.

One thing that founders always underestimate is how hard it is to recruit.
