I really don't see how interest can simply come from positive experience if there's no affinity. I've never tried Mongolian throat warbling, so I'm neither here nor there. And trying it doesn't mean I'll become interested in it even if I enjoy doing it a few times. Like I've generally had positive experience doing math (as far as I can recall), but I haven't gained any interest in it. It just isn't there. And that means I'd never join a math club, for example; I'd find it dull, even if I had friends in it. Same for a myriad of other things. It'd be pretty overwhelming mentally if one were to be interested in everything they tried and had a positive experience with IMO, which is why people specialize.

And conversely if I think hard enough, I can probably come up with something I never had early positive experience with but still pursued because I found it interesting. I'm also very interested in traveling in space, but I definitely don't have any experience, positive or negative, and likely will never gain any. I'd totally join a club that talks about traveling in space in a heartbeat though.
