The question is a bit too vague to answer, there’s not really any right answer.

Just - find what you like to do with it, and go for it. Want to make a game? Maybe play around with Godot or unreal engine or something.

Do you have any repetitive task that you’re doing a lot that you could maybe automate? - try doing that.

You can read some books or watch some tutorials or something, but the best way to actually learn is to actually program.
