The other piece besides focus for execution is intensity. Startups only work at a fairly intense level.

Remember that you are more likely to die because you execute badly than get crushed by a competitor.

There are 3 things I look for when I hire people. Are they smart? Do they get things done? Do I want to spend a lot of time around them?

Great execution towards a terrible idea will get you nowhere.

Share results (financial and key metrics) with the company every month.

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

It really is true that you become an average of the people you spend the most time with.
