These all sounded really bad, but they turned out to be good. If they had sounded really good, there would have been too many people working on them.

You can have a startup and one other thing, you can have a family, but you probably can't have many other things.

We've seen a lot of data at YC now, and the most successful companies and the ones where the investors do the best... end up giving a lot of stock out to employees- year after year after year.

In the early stage of a startup, hiring senior people is usually a mistake. You just want people that get stuff done.

Before product/market fit, your only job that matters is to build a great product.

Most startups are not nearly focussed enough. They work hard...maybe, but they don't work hard on the right things.

... the thing we see wrong with YC apps most frequently, is that people have not thought about the market first and what people want first.
