I don't look at this like that, not any more at least.

I guess it depends a lot of personality and the type of work you enjoy. I thrive at early stages, where most things a built on common sense and you have enough power to shape things into something meaningful.
These days I try to appreciate "the process" (day-to-day) over "results" (exits).
You don't really have too much control of how things unfold in your life really, be blessed you are alive and kicking.
Do I say money is not important? Of course not - it's very important, but in a challenging times you have to test your limits and re-assess your priorities (whether you like it or not...)
It's easy to look at things in hindsight - the question is what is the alternative? 5 years of what?
