Most startups are not nearly focussed enough. They work hard...maybe, but they don't work hard on the right things.

Another way of looking at this, is that the best companies are almost always mission oriented.

The tenth social network, and limited only to college students with no money, also terrible. Myspace had won.

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

So if you want a culture where people work hard, & pay attention to detail, focus on the customer, are frugal: you have to do it yourself.

Mediocre founders spend a lot of time talking about grand plans, but they never quite make a decision.

Facebook has this famous poster that says move fast and break things. But at the same time they manage to be obsessed with quality.
