I’m giving you sincere advice. There are people on here who will hate you if you try. As for the question, Nostr has a very small user base, and an even smaller base of people willing to zap. In general, V4V takes time and patience as you create whatever it is you love to create and find your community/niche of people that enjoy it. So for now, I’d say that no, it’s not possible to make content creation on Nostr a full time job. But content creation in the larger sense absolutely can be, and Nostr can be part of that strategy.
