Some things that helped me:

Finding your niche(s) Trying to write about what you think other people are interested in when you're not in it - that won't work and will lead to bad posts. Write about what you're interested in - if that is crypto-stuff, then write about crypto-stuff (clearly not my nice). But we all have more than one interest, write about those, find others who do, join their community or build one. My main niches are needlework (knitting etc.) and table-top roleplaying, I'm interested in bread baking and gardening, too, and read and write about that. You love carrier pigeons or collect subway tickets? Write about it! Even if you don't find other people who share that interest you get yourself noticed. Being the "carrier pigeon guy" is better than being one of thousands other unnoticed writers :)

Engage in your local community That's especially important for those non-native English speakers. The German community gave me a lot of help and information, through posts and Discord.

Discord Yes, a social media app that helps you on a blockchain. Sounds absurd, but it works really well. Fast answers to problems, working on building your community or simple smalltalk - it can be place for everything you want it to be.

I'm still small-fry but I made it to 350 rewarded SP in not yet 250 days and am more than content with it :)
