I've tried becoming a nicer person in order to expand my social circle because apparently that's the foundation of your mental health. The result is that I met lots of people whose presence I simply do not enjoy. The people whose presence I do enjoy have shit to do and I see them once every few months at best. My prospects of meeting a partner are epsilon, which a major source of frustration for me. I've tried having hobbies but everything gets boring after the initial phase of "wow I love doing this new thing". I've tried sticking to things out of pure discipline and I gained skills, but fuck, it's not enjoyable. I'm not invested in my career because getting a significant raise at my company is pretty much impossible, and if I want to switch companies, I'd need to leave local maximum. I don't enjoy spending time with my family because they're not interested in getting to know me, they just want me to perform the theatre of "How's weather? Ah it's a nice day today".
It's not possible for me to be emotionally invested in anything because I'm profoundly disappointed in life. I want a refund.
Volunteering is also nice. People are there because they want to and at the end of the day it gives you a nice feeling of doing something good.
For home use, it seems like you could rig up some heavy stones on pulleys to do the same thing could be fun because you’d get to physically see your batteries filling up. Back of the envelope calculations suggest that an array of ten 10-ton concrete blocks lifted 10m in the air could power a house for a day (ignoring generator inefficiencies)
