I got lucky at a few startups in my mid-20s and now in my early 30s feeling a profound loss of motivation to continue working or developing a career after achieving a comfortable worry-free level of financial success.
Perhaps part of it is that I’m not that motivated by either money or status or power.
Has anyone been in a similar situation and how did you deal with it to find motivation again?
These are both kind of vague questions, but that's because you have to answer them for yourself. If the answers are the same, then you have a goal to work for that will probably motivate you quite well. If the answers are different, then you can decide based on whatever feels best for you.
You might also consider posting in some of the FIRE-related forums, particularly on Reddit. There are some good resources there, not the least of which is the community of people who can tell you how they approached questions like this in their lives.
