Losing focus is another way that founders get off track.

You have to find a small market in which you can get a monopoly and then quickly expand.

When it comes to starting startups, in many ways, it's easier to start a hard startup than an easy startup.

The best source by far for hiring is people that you already know and people that other employees in the company already know.

Remember that the idea will expand, and become more ambitious as you go.

One thing I tell startups all the time is that the best way to grow is to make their product better.

Firing people is one of the worst parts of running a company. Actually in my own experience, I think it is the worst.
