It seems like you have experienced a lot and that the field you are passionate about has nothing left to offer. Just because you’ve reached the top and there’s nowhere left to go, doesn’t mean that there aren’t thousands of interesting opportunities elsewhere. I would love to say that traveling and doing all these new things would be helpful, but at the same time, chasing a checklist will just leave you unsatisfied. Maybe move somewhere else? Meet different people? Live slow and relax?

Other people can give you their advice, but you know yourself best.
