I know that being unhappy (as an individual) can lead to inhibition. Procrastination, addiction, escapism, doomerism etc. "Happy people" (whatever that means) do change things and are interested in change, but not necessarily in revolution.

I think a revolution can only happen if some people are so miserable that they have nothing to lose. Because the amount of people who aren't miserable, and are still willing to sacrifice their comfort to help working towards a goal greater than themselves is pretty low.

Is it more important to focus on the former or the latter type? idk!
