However, if you ask me to pick one specific project, I get overwhelmed because I don’t know what’s reasonable.

I don’t know enough to know if my ideas are achievable, or if I’d just be bashing my head against the wall. I don’t know if they’re laughably simple tasks, multimillion-dollar propositions, or Goldilocks ideas that would be perfect to learn a coding language.

List out some ideas you’re thinking of. While it may not be obvious to you, someone who is seasoned (me or someone else) might notice at least a general theme or idea to point you in the right direction for where you should go and what you should learn, regardless of if the projects are reasonable.

Note - Most projects take teams to realize, so if your ideas are too large, they might not generally be feasible alone.

What are you looking to actually do with your programming skills? That will heavily influence which languages to recommend you learn. Do you want to make websites? build games? do AI stuff? Create enterprise-level software? something else?
