Someday, you need to build a business that's difficult to replicate. This is an important part of a good idea.

One of the great and terrible things about starting a start up is that you get no credit for trying.

We hear again and again from founders, that they wish they had waited to start a startup until they came up with an idea they really loved.

The best people know that they should join a rocketship.

The most common post YC failure case for the companies we fund, is they're incredibly focussed during YC on their company... and after they start doing a lot of other things. They advise companies, they go to conferences, whatever.

A related advantage of mission oriented ideas, is that you yourself will be dedicated to them.

In the beginning of a company, there is no management and this actually works really well.
