But you are special. Maybe not special in the sense that you are guaranteed a certain fame or fortune, but you have the same amount of responsibility as anyone else. This is why people have mid-life crises, they wake up to the fact that they do have a unique self with unique needs, gifts, and values. With limited time remaining, it's crucial to find your gifts and use them to maximum capacity.

For my own mid-life crisis I learned about my personality type and found that I had a bunch of gifts in analysis, measurement, and framework building of which I wasn't aware. So I put them to work and lost 100 pounds. Now I'm trying to FIRE and think it might happen.

If you're interested I recommend Dario Nardi's book, 8 Keys to Self- leadership. It's incredibly dense and the exercises within can't really be completed, or rather, the psychological development opportunities within probably won't be reachable for anybody in their totality. The author says he's still working on the various facets himself. But it'll give you a sense of where your gifts are, and that makes life a lot more bearable.
