At the beginning of my learning cycle I rarely play (usually a bad idea) and become obsessed with studying. It feels like I am making huge strides as I solve problems and research strategies. Spirits are high.
Once I leave the studying phase and begin playing games I quickly learn that the concepts/techniques I studied are difficult to apply in real game situations. Self-loathing sets in and I usually stop playing all together. You can see when this phase sets in because I turn on vacation mode on my OGS account.
3. Burgeoning confidence:
Eventually, I get over myself and start playing games again. After about a dozen frustrating losses I manage to get a handle on the concepts I am trying to integrate into my game. My rank usually improves 1-2 stones over the next, approximately, 20 games.
As I reach the limit of my improvement for this particular cycle I become frustrated that I am no longer winning as much. Perfectly natural, but still irritating.
After Frustration, I come, full circle, back to the studying phase.
I have found it useful to recognize these stages. Particularly the Despair phase. When I see I am coming up on that stage I try to play more games in order to get through it as quickly as possible. I am not always successful, but I get a little better each time.
Really, that's the goal with go. You just need to become a little better every day. Recognizing and understanding your learning process can help you fine tune your approach to learning the game.
Keep at it! Try to figure out what works best for you. It isn't easy, but few things worthwhile ever are. :)
