I've thought about it, but then again, my interests change all over. And the things I actually want to do, and to some extent, I'm passionate about, aren't really business perspectives I guess. Mainly because it's not the "job" itself that appeals to me, but the endproduct. Right now I do enjoy graphic design/work, but only because I have something I want to do with it. If I'm done with my personal project I'll most likely abandon that field until I have a new "goal" that uses these techniques. And the same goes with all my creative endeavors. I'll only pick up my guitar or turn on my synthesizer when I have an absolute urge to write a piece, which probably is already written for 75% in my mind.
There's a field I care about enough to, in theory, make it a thing. I don't know if it's sustainable as such though. I always had a strong interest in games (card/boardgames) and wouldn't mind owning/running a store that sells and facilitates those products. A store that's big enough to offer gaming spots for people. Perhaps even add in some related products like paints, brushes, specialist lamps and whatever you need for tabletop wargaming (and the entire painting thing that comes with it).
Some experience tells me that my city, and pretty much the general area here is not ideal for it. There's no real market for it here. I've seen a few stores within the 30 mile radius go bust while I thought they were the best places I've ever been to. The ones that actually manage to keep around are mostly stores that offer no gaming space as well as specialise in other stuff more than said gaming products. There's a store that actually is trying to get out the gaming side of the products, since it's actually a comic book store. Which I guess is fair enough. The reason the owner wanted to get rid of it, is because the profit margins on it are so slim the shelves could probably stock more profitable items as well as a lot of silly regulations some gaming companies pose upon stores.
Add in that to start a business like that you would need a lot of money to start off with. I did my math and looked how much of a starterloan I could get, and I found that this was not enough to get started just on that. And since I don't have a job I can't really put any "reserves" into that. Add in that a businessplan needs to be approved and a bank will surely look if your plan has a viable future, even in times like this supposed crisis. Luxury products, that are obviously "luxury" priced. Having a decent place to run your store is another issue. Prices for a big enough store are jacking up way too much. The last store I've frequented was about 3000 bucks in rent a month, and of course it went bust, it would never flip over 3000 bucks in products and make a profit as well. Hence it went bust. At some point they got subsidized by the local government because they doubled as a hangout for teens, but then come cutbacks and it clearly needs to go. But that's how the store kept going for about 3 years... the owner and his family are pretty in debt and on social security now.
I've talked to most store owners in the area from both current and former stores so my knowledge isn't just from nothing.
Owning a business just by myself doesn't seem smart and since I don't have a big social group of people I trust enough, it's hard to find a business partner.
Also looking into store policies here, laws, regulations... it doesn't sit well with me. We have pretty strict laws for store opening here and I'm quite sure that a place for teens and adults to hang out and play a game (and as such spend leisure time), isn't suited to be a 10 in the morning to 6 the evneing opening thing. I'd rather have my store open at 3 in the afternoon and close at 12 in the evening or so. And open on sunday...
To some extent this actually came from looking into advice from a therapist. Therapists all in my life concluded that I do not function with a boss and should run my own company if anything. So that's pretty much the best way to get employed, based on what experts told me. It does become a problem when even "being your own boss" is limited by law, because you even have different ideas how to run your business and it keeps conflicting.
