> Then I realize that success (in terms of an exit or something similar) can't be the goal: I work on startups because I like building things and I want to change the world.
While the above might be a commendable personal goal, startups are indeed created for their possible exit value. The vision, the tech and the kind of things you end up working on are commanded or at least heavily influenced by these circumstances. In that sense there isn't too much difference from working for an innovative established company (except you don't get a shot at the money pot).
The startups I work on have that as a top level goal, absolutely and 100% - as a person, you have to focus on and reward the process as much as the potential result, or it won't work. Paul Singh is fond of saying "we always celebrate the result, but we need to celebrate the process". Putting more people in the right process will produce more positive results, even if not all those people can achieve the massive results we're learning for.
