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.

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.

Ultimately, I don't believe that you can build a company without a lot of effort, and that you need to lead by example.

Treat customer support as a product.

You can build the most important companies in history with a very simple to describe concept. You can market products in less than 50 characters. There is no reason why you can't build your company the same way. So force yourself to simplify every initiative, every product, every marketing, everything you do. Basically take out that red and start eliminating stuff.

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

If people start going to a desk, some one individual employees desk and they don't report to them... it's a sign that they believe that person can help them. So if you see that consistently, those are your barrels. Just promote them, give them more opportunity as fast as you can.
