When you have no idea what to do in your game or whether what you did was a good idea, I know it can be tempting to just open a book and hope to have it explain everything. I’m not saying that you should not read Go books; you should!
But way more importantly: learn from stronger players! There is no better way. Get reviews, get teaching games, replay pro games and watch lectures. A stronger player can tell you which books you should read next, and which problems are suitable for you to solve. If you can find some stronger Go players in your area, that would be best.
You can get reviews and teaching games right here on OGS.
