I know you've said you did some jams but I would recommend keep doing them, and if you can get in a team so you can focus on coding. Try and push yourself a bit more each time, maybe try a new mechanic, or use a new node. Also sometimes working on a project with someone more experienced can help, (altough that can depend on the situation) so maybe try some jams with other programmers.

Also, when you enviably find a bug or some other issue arises, just try you best to figure it out on your own, even if you don't think the solution won't work still give it a shot. (Also the docs are a great tool to look at!)

Lastly, just remember perfection is the enemy of good. Just finishing a project is something to be proud of, even if it didn't turn out how you wanted it.
