Press releases are easier to write than code, and that is still easier than making a great product.

Stay focused and don't try to do too many things at once. Care about execution quality.

Here's a good rule of thumb: don't worry about a competitor at all, until they're actually beating you with a real shipped product.

Most things are not as risky as they seem.

Wait to start a startup until you come up with an idea that you feel compelled to explore.

A board member of mine used to say sales fix everything in a startup, and that is really true.

The best ideas often look terrible at the beginning the truly good ideas, don't seem like they're worth stealing.
