Yeah, a few of the other comments assume that the office is the only place you can find companionship. That's an issue. Just like it's smart to set up boundaries between your WFH area and your rest and relaxation area, you need a set of friends outside of your coworkers as well.
It's a kind of optimization when you think about it. An optimization of the worker. His lifestyle is modified for maximum time and energy invested in work. All other needs (sleep, socialization, leisure, eating, exercise) are reduced to a tiny high-efficiency pill form.
I currently struggle to buy anything that would have a positive effect on my happiness. I got a motorcycle two years ago, and while I do pretty few miles, it provided quite some happiness (going on Saturday rides with a friend, general added feeling of "freedom" because of having a way to escape the city and also do short trips I usually would fret about which public transport to take or if it makes sense to use carsharing). Another thing that comes to mind is my Vacuum cleaner - I spent money on a cordless Dyson and I can clean my small flat in 15 minutes now (robot doesn't make sense due to the size).
I have the budget to buy some live improving stuff, but I don't see anything.
