Don’t suggest hobbies or human contact. It’s been suggested and it doesn’t work.
I have a job I don’t particularly hate nor like, some coworkers I get along with others are just morons, I go to work, then buy groceries, go home, eat, watch tv, go to bed. Rinse and repeat.
On my free days I do sport and watch pirated netflix. I don’t spend much money on clothing or media and save most of my paycheck. What for? I have no idea. I don’t eat out because I like cooking my own food and restaurants are expensive and the food is bland.
Everything is so expensive nowadays btw…
Most people bore me. I’m like an atheist monk.
I don’t want to kill myself or anybody fwiw. It’s like I don’t give a crap about anything or anyone and don’t see what’s the point of living.
I don’t want to travel because it costs money.
As soon as my cognitive abilities start to fail I’m going to be very easy prey for any online scammer.
So you‘re boring, arrogant and not interested in anything. Gotcha. Still enough to do for somebody like you, no worries:
Okay, you do like cooking. If that’s something you enjoy you might want to improve it. Watch some cooking videos on YouTube. Read some books about it. Experiment a bit. Bring some of it to work for your colleagues that aren’t total morons. No sweat, no pressure, just have a bit of fun.
Okay, so you do sport in your freetime. Good. Maybe set goal for something. If you are into running you could train for a marathon or just for a random sportsevent in your area.
What music do you listening to? Are there concerts of bands you like nearby? Or a bit farther away, giving opportunity for a nice weekend trip? You don’t have to stand right in the middle, you know. Just jam to the music where’s a bit more space around you.
Get a pen and a notebook and write what comes to your mind. Honestly, I can’t stress enough how important that is. Go. Write. Old style analogue. Bring order to your thoughts. Or the opposite, just vomit them on page. As long as you write.
Buy a motorcycle and drive around. With aim or without.
Learn to mix cocktails and or get into whiskeys.
Learn to build a pc and buy the new monster hunter or just some other game you like.
Learn bushcrafting and to wildcamp and sleep in a hammock beneath a tarp in the mountains / down by the river / at the local park.
I wouldn’t recommend it it to somebody else, but: Pay prostitutes for sex. You have money and that’s the most effortless way for sex that requires the least human interaction. No clubbing, no flirting, no dating. Perfect for you.
Visit lost places. Climb on cell towers or building cranes at night and enjoy the view. Go for a night swim. Go rooftopping.
Set a goal to do something crazy every day. Or something kind. Or both.
I would recommend travelling, but I think you’d be still bored and uninterested just at a different place. However I think it can be Eye opening to see how people live somewhere else.
That’s pretty much it. Good luck.
