It sounds like you’re looking for a hobby. It’s normal to feel like you have no “thing” to do, that’s why people do hobbies. My advice would be to pick out 3 things you’ve never done before and go try them. If you like one stick with it, if you hate them all try something else. Most people will not be world leaders or have a global impact but you can make a meaningful impact on a smaller hobbiest community. My 3 reasonably low cost suggestions are 1. Rock climbing (there are gyms everywhere if you Google, find one that is doing a discount night or other event and go) 2. Biking (contact a local bike shop to see if they do community rides, they may even let you borrow one of you don’t own a bike) 3. Book club ( if you have free time it’s easy to read and chances are the club is more social then talking about the book)
