I'd recommend playing a lot of games. I'd recommend reading a lot. I'd reiterate the advice everyone gives: start small. It might seem like your game would only work if it is of some imaginary size but 9 times out of 10 it is not the case. Great games can be very small. There's plenty evidence out there. Great games usually do one thing really good. Bad games usually do many things averagely. My game suffers from this as well, it isn't clear in what it wants to be (are you a chess player manager or a chess player?).
I'd recommend looking after your health and going for consistency. Work every day.
-Yes, keep working on your craft. The craft is making games. It is hard and it is complicated but that's where the joy comes from. Keep making games and keep improving the craft and we'll get there.
