Low-cost backpacking in 3rd world (obviously not during covid), hiking, alpinism, climbing, via ferratas, ski touring/alipinism, skiing, paragliding, diving... plus some more usual sports/activities like biking, running, swimming.
It doesn't have to be that many (which is hard to manage with 100% employment), even 1 would suffice if done properly. I have a kid now, second possibly on the way, so even without covid some of this is/will be massively scaled down. But I still want to pick up new ones - right now its precision target shooting and archery.
Its more about mindset - if you feel you have a great life, money is just a tool to keep it. For that you don't need terribly much, heck some full time climbers live in camper vans for the whole time. On the other hand if you don't enjoy your life, money won't make it magically better, sometimes the opposite.
And no I don't sell some stupid coaching :) Those are just my own experiences
