The startups that do well are the ones that are working all the time.

One of the pieces of advice that we give at YC is: try to work together on a project rather than just doing an interview.

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

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

... for the top twenty most valuable YC companies, all of them have at least two founders.

If you're not in college and you don't know a cofounder, the next best thing I think is to go work at an interesting company.

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.
