You can basically change everything in a startup but the market.

In general though, if you look at the track record of pivots, they don't become big companies.

You also really want to take the time to think about how the market is going to evolve.You need a market that's going to be big in 10 years.

If you don't need it yourself, and you're building something that someone else needs, realize you're at a big disadvantage.

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.

Everyone starting a startup for the first time is scared, and everyone feels like a bit of an imposter.

As you grow, the productivity I think, goes down with the square of the number of employees if you don't make an effort.
