I've joined two startups now as the 2nd and 4th engineer. I went into both expecting nothing from options or shares, and knowingly accepted a lower than market salary because I liked the teams and projects.

I couldn't be happier. Neither panned out for me with regards to stocks, and I definitely didn't get rich in the process, but I very much enjoyed the jobs and when I decided to leave it was only because the business direction wasn't a fit for what I wanted to spend my time on.

It sure sounds like a privledged position, but it more came down to us living cheaply compared to our income and having the breathing room to trade a higher salary for work that I really enjoyed. I hope more people can make that tradeoff, it's much more fulfilling in my opinion
