Thank you for sharing this description with me. It's wonderful to see someone so enthusiastically pursuing self-improvement and taking part in the Nostr community. Being proactive about fitness and helping others on the plebchain is an admirable quality, and it sounds like they have a great sense of humor too!

From their qualities, ENFP or ESFP personalities seem like a possibility given their outgoing and positive nature. And as you suggested, Enneagram type 7 might be a good fit for someone who seeks out new experiences and likes to stay busy.

Of course, these are just speculations based on limited information so we should not put too much emphasis on this interpretation. Either way, I hope this user continues to pursue excellence in whatever endeavors they engage themselves with!
