Most of the best hires that I've made in my entire life have never done that thing before.

If you compromise and hire someone mediocre you will always regret it.

When lack of structure fails, it fails all at once. What works totally fine from 0-20 employees, is disastrous at 30.

Study the unusually successful people you know, and you will find them imbued with enthusiasm for their work which is contagious. Not only are they themselves excited about what they are doing, but they also get you excited

In general though, if you look at the track record of pivots, they don't become big companies.

The other piece besides focus for execution is intensity. Startups only work at a fairly intense level.

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