Although I've done quite well for myself, I'm not remotely near this level of wealth, so my insight and advice is likely just plain wrong.

Building on an analogy you used, you've let society dictate your "unattainable main quest", but then actually managed to attain it, losing your core sense of purpose in the process.

So pick a new unattainable main quest and internalize it, before proceeding with your life.

Easier said than done of course. You're fighting to replace a goal that was repeatedly forced into you from the early days of your conscious existence. How hard this will be comes down to your individual mental composition. It might be impossible. It might be easy and just require willful thought on your part. There are probably therapists that specialize in exactly this kind of situation.

Good luck!
