I'm not big in the NG scene (nobody knows me besides a few old mods that I keep in chat with), but fame just happens.
I'm not saying I'm popular, but with very little advertisement and some networking/interaction with other artists on Soundcloud has helped me reach almost 300 followers.
I'm not saying that I'm the best musician, but occasionally I manage to write a cool tune that garners people's attention, from bedroom producers like myself to some massive names in the music biz.
Fame is kinda cool, no two ways about it, but I do my work for the fun of writing music, with fame being a handy and fun little by-product of the joy I get form writing music.
And I understand, too, that some people find little joy in making music without the fame. And that's fine! I'm not going to slag you off for not being "about the music", but you have to realise fame is not a big thing. There are a quadrillion other bedroom producers out in the big world doing their thing, and only a tiny handful of those producers get big.
Some producers get big worldwide (read: Dillon Francis, Noisia, Skrillex, Diplo, Baauer), some get big in a certain scene (Donny, Katharsys in the dark DnB scene; Renard in the furry scene; Anamanaguchi, Sabrepulse, trash80 and little-scale in the chipmusic/retrotech scene; etc), and some get big in their circle of friends.
If you're doing it for a sense of self-validation, remember that fame =/= talent. Sometimes it does (Skrillex's synth work is killer, Donny can brickwall a tune harder than any human or machine alive, Diplo knows how to jump on a bandwagon and keep it going for a while), but a lot of my favourite artists are my friends, and they're doing absolutely killer things with their music (while being on a Soundcloud follower count of anything lower than 500).
Success is subjective, too. So there's always that :P
