Line any be language, use it.

Pick something small that would be fun and useful, and write a prototype.

Repeat.

Whatever is useful to you.

How about a nostr client? Read and write a message to a web socket?

Or something that reads a web page and extracts urls?

Implement a a Ceaser cipher encoder, then write a breaker.

Start with simple utilities, and read up about libraries that would help, and start using them.

Your learning will be all over the place, and sorry, and that's ok.
