Same situation, I truly empathise because it really does seem to take a lot of purpose out of everything. What I’ve found is that you need to replace money/salary/financial success optimisation (assuming you spent a lot of your life and energy to this point focused on these, much like I did) with something else totally unconnected with being measured in that way. For me, I am focused on proving myself as a guitarist…
This is my dream. Having enough money to be able to dedicate to things I like, trying to be good at something without worrying about money, or time, or being tired after work. Open a bookshop, being a rare book dealer, open a small museum about an author, research on a particular topic and write books... That would be the ultimate dream, though I am sure I won't ever be near to fulfill it.
Money doesn't buy time, whatever you like you'd be better off starting now then at some point in the future when you think you have enough money because you make the fallacious equation "enough money = enough time" but that is wrong because mental and physical acuity diminishes with time so a minute in your 20s is worth more than a minute in your 30s and much more than a minute in your 60s etc...also odds of mental/physical illnesses increase, life gets in the way in modalities that you don't expect yet, inflation, collapse of society...in one word entropy.
Money cannot beat entropy or slow it down
