I’ve thought about this a lot. What it comes down to is that the only true agency you have is by strengthening your mind. That’s really the only solution I could come up with.

Because at the end of the day everything gets old - every act, job, etc. (hedonistic treadmill).

And having complete freedom isn’t a solution. You’re still trapped within your own head 24/7.

Taking time to pursue meditation and other activities that help you be happy no matter what the circumstances of the external world seem like the best choice of activity when younger in order to build agency.
