What do I do with my life?

I am 30, European, upper-middle class with a cushy job and a mortgage. I tried having some hobbies, and honestly, nothing really gets me excited. Like sure, I can spend some time on things, be it sports or vidya or painting, but it doesn't really "click". I always liked spending time with cool people, but I'm just tired of fruitless search and decided to become a shut-in. Consequently, raising a family is not going to happen.

I'm really missing the feeling of moving towards some bigger goal. My life is just same optimized loop every day.
