Building alone doesn't get you zaps. If you are a socially awkward introvert who has an issue with sharing anything on social media, you won't get zaps no matter how good you are at building whatever you are building. On the other hand, if you are a big extrovert and get the feel of the community, you get tons of zaps for shitposting alone.
I don't mean building or creating in the traditional sense. I mean build your community, stack, family, content, anything. And then talk about what you built. Creating anything goes very far on Nostr. Most people here understand value for value and appreciate Proof of Work.
