The main thing I’ve learned in 40-plus years as an entrepreneur is that nobody knows anything. Nobody knows if your idea is good or bad. You don’t … - Marc Randolph

Personally, I’d rather have someone who executes a mediocre idea brilliantly than someone who talks about a brilliant idea forever.

Execution beats perfection every time.

You don’t beat competitors by doing the same thing slightly better.....you beat them by doing something different that matters more to your customer.

If everyone’s fighting over price, find a better experience.

If they’re all optimizing convenience, find a niche they’re ignoring.

The key is focus.

And solving one painful problem really well.

Exceptional people put a premium on working with other exceptional people.

This requires that you not only hire well, but cut smartly.

It means taking the “no jerks” policy seriously, even for high-performing jerks.
