Yep, try to work on a speficic project for a period. Focus on nailing and understanding the main features you want to implement in that (UI,code,visuals, music, animation, etc.) then finish it. Once your game is finished (of course not polished af but just finished) you can decide to go to the next one or polish it. The main point is you have to understand new stuff while getting errors or things that are less known to you, so you improve your skills over and over.
