It takes years and years, usually a decade, to create a great startup.

If you're not in college and you don't know a cofounder, the next best thing I think is to go work at an interesting company.

Growth solves (nearly) all problems

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

For most of the early hires you make in a startup, experience doesn't matter very much, and you should go for aptitude.

Be suspicious of any work that is not building product or getting customers. It's easy to get sucked into an infrastructure rewrite death spiral.

Ideas by themselves are not worth anything, only executing well is what creates value.
