I'm sorry for taking a week to respond, it's been a stressful little while.
To keep this short, because you wrote a lot (thank you by the way, I can tell you put a lot of effort into that), I'm going to respond to each idea one by one, as few sentences each (retroactive edit: I never manage that, do I?).
Exercise or Zumba class: I like doing things that are physically exerting not for the sake of the exertion itself, but because I enjoy the activity; for instance, I enjoy walking because I enjoy the trees and the sky and occasionally when I'm further out of town, the interesting plants and mushrooms of the local forests, but I wouldn't enjoy walking on the spot for the same length of time, so exercise itself isn't something I'm fond of.
As for zumba specifically, I don't know what that is (I had to look it up)... I think the fast-paced full-body movement of that might literally kill me.
I can walk for miles but a run could be the death of me, and that is no exception.
Exporing music and playlist making: my offline music collection (which isn't my full collection, just the songs I've backuped) has recently reached around 2,400 songs, from a variety of musicians across a variety of genres; I'm on my second pair of hi-fi headphones, and I've had a very exploritory relationship with music all my life, so I think I've got that down.
Also yes I do playlisting, but honestly so much of my music is hard to find or semi-lost media at this point, playlisting is generally impractical; it's a downside of obscure tastes.
Drawing: I gave up on drawing around a year ago now, and rather ironically given your suggestion, I gave up because of sketching.
I think it's the least fun part by far, and as someone who draws lineartless (and always has, as lineart baffles me for some reason) and finds shading to be the most fun part, sketching is not only the most important, but also, by far, the longest.
I would usually spend about one week (sometimes longer still during the worst of it) trying to get a just a single sketch down that was workable (and getting one at the end of it was rare), before spending 3 days at most (and even that was dragged out so I would have more time to enjoy it) doing the coloring and shading; it was just too much, and my mental health is much better now that I've quit.
Hot drinks: I make teas all the time, usually herbal teas, and it's great.
Too bad all the interesting teas are so expensive though.
Besides teas are the only hot drink I really care for; I like my drinks soothing, and outside of that I'm not fond, really.
Writing: I have been writing for the last 3 years; it is my only reliable hobby. You might've realized the fact that I'm a writer by how terribly written this post has been
Language and instruments: I'm planing on learning french, but that's so I can get into university, not really for fun, and I'm kind of doubtful I'll enjoy it. If I wanted to learn a language for fun I'd be learning Latin or Greak so that I could read the originals of the epics, or greak poetry, but that's kind of a later-in-my-life goal; I'll be getting into that in my 20s when I have better resources, I see no reason to rush that.
I used to play the violin but my father kept pushing me on it to a point where it became a chore rather then a hobby, so I decided for my own sake to quit (I didn't even tell him, it wouldn't be worth the energy). I'm not really interested in any other instruments, so learning to play another one doesn't sound very appealing.
Long showers and moisturiser: I don't know how far back you've read into this thread Micheala, but I kind of already responded to the shower thing.
I rather baths over showers (I have a bad back, there's no way I'm going to do all of that leaning just to shave my legs) -> I have a habit of getting turned on in the bath (it's a comfortable place to fantasise) -> masturbation instead of selfcare (what we're talking about alternatives to, right now).
It was a kind thought, but that doesn't work for me.
Moisturizing meanwhile, well, I react to most moisturizer, and the only one I have that I don't react to is quite thick and a little unpleasant to apply, which doesn't exactly sound like the relaxing experience you're likely imagining.
To give a sense of scale (for lack of a better term) for when I say I have sensitive skin - I'm allergic to all soap (I use vegatable glycerin, which is a sugar~alcohol, because unlike soap atleast that doesn't physically hurt to apply), I get a severe burning sensation that leaves lasting marks when expost to Aloe Vera, and least believably, I once spoke to a dermatologist who was in her... must of been 80s given how long she worked there, who said that in the 60 years she'd worked in skin health, I had the most sensitive skin she'd ever seen (although maybe she says that to all the girls
) - I mean, if I touched that stuff they use to wash crude oil off of baby ducks in those Dove advertivements, I'd be recovering for days.
It was very kind of you to give me a list like that but I don't think I could get anywhere with those.
If you have any other ideas, however, I'd love to hear them!
