There's at least a hundred times more people with great ideas than people that are willing to put in the effort to execute them well.

Many of the best YC companies have had phenomenally small number of employees for their first year, sometimes none besides the founders.

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

By the way, that's my number one piece of advice if you're going to join a startup: pick a rocket ship.

In general don't start a startup you're not willing to work on for ten years.

If it works out, you're going to be working on this for 10 years.

... and you can only have 2 or 3 things everyday, because everything else will just come at you; you know fires in a day.
