In general, it's best if you're building something that you yourself need.

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

Most good founders that I know at any given time have a set of small overarching goals for the company that everybody in the company knows.

You're saying no ninety-seven times out of a hundred, and most founders find they have to make a very conscious effort to do this.

Investors will sort of like write the check and then, despite a lot of promises, don't usually do that much; sometimes they do.

Obsess about the quality of the product.

It's really easy to get PR with no results & it actually feels like you're really actually cool, but in a year you'll still have nothing.
