Money is just means, similar to how you converted eth to real money you need to convert real money into real experiences. There are doors open to you now to travel to scenic places, experience different cultures, experience different cuisines, learn new things for which you never had time get exposure to new skills you may or may not like them. When i got retired i tried horse riding although i never had any inclination towards it but just enrolled it to see where it goes did not liked it much, tried shooting liked it, tried swimming liked it, tried ski-ing did not liked it, tried singing i was really bad at it. Finally settled for building sofware as i guess i like building stuff as hobby i just don't like it as profession where i have to deal with deadlines other constraints etc. Experiment and see what you like.
Last but not the least you don't really need money to do most of these things, you arbitrarily decided that you needed money because society/culture/conditioning made you believe it. you can be happy without it as well if you realize that you may as well wonder what was the fuss all about.
