Most founders have not managed people before, and they certainly haven't managed managers.

It's difficult to get large groups of people, to the extreme levels of focus and productivity that you need, for a startup to be successful.

You don't get to make their decisions but you do get to choose the decision makers.

At the beginning, you should only hire when you have a desperate need to.

There are exceptions of course, but most companies start with a great idea - not a pivot.

Losing focus is another way that founders get off track.

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