Bitcoin requires and deserves ONGOING learning IMO. Stage 1 is learning the beginner basics, getting a cold wallet and managing yoir own keys. It's a very big deal to just get here. So congrats! 👏
But then there's *so* much more. Continual practice is very useful for yourself, but also for adoption and spreading awareness...

Use a sidechain/federation.

Go to a meetup or conference.
Code something useful.
Gift someone a Satscard.

Listen to a new podcast.
Etc. I know I missed some...
