Usually when you hire more engineers, you actually don't get that much more done, you actually sometimes get less done.

You generally know when someone asks you to do something- am I more writing, or am I more editing? The editor is the best metaphor for your job.

The more you simplify, the better people will perform. People can not understand and keep track of a long complicated set of initiatives. So you have to distill it down to one, two, or three things and use a framework they can repeat, they can repeat without thinking about, they can repeat to their friends, they can repeat at night.

I don't believe ever in shared office spaces. Peter talks a little bit about this, every good startup is a cult. It's very hard to create a cult if you're sharing space with people.

Building a company is basically taking all the irrational people you know... Putting them in one building and then living with them 12 hrs a day at least.

I walk into a company office and I can tell often whether I'm gonna invest, as soon as I walk in.

Force yourself to simplify every initiative, every product, every marketing, everything you do.
