The single word that matters most I think to keep the company productive as it grows is alignment.

You need unstoppable people. You want people that are just going to get it done.

If you don't need it yourself, and you're building something that someone else needs, realize you're at a big disadvantage.

Why couldn't it have been done 2 years ago, and why will 2 years in the future be too late?

So you should always stay on top of people's vesting schedules.

In general, it's best if you're building something that you yourself need.

Investors will sort of like write the check and then, despite a lot of promises, don't usually do that much; sometimes they do.
