This is really interesting. What is that very very special treatment that can change the network in the brain responsible for focus? Any links or further details about it will be really appreciated.
It's called Neurofeedback training. I was fortunate enough to find the person who pioneered this breakthrough treatment and she was only 30min away. There are a lot of scams so please do your research and make sure the person running the clinic has academic weight. I was fortunate to find the right person. It essentially boils down to connecting your sensory system with your motor cortex and it put you into a state that high performing athletes and Buddhist monks get into. I will also mention the way I did the treatment probably gave me above average results. So if you are doing it, you should message me so I can give you the techniques I figured out in the process.
This is very interesting. I have a similar outlook on abilities as you, but only partial/lesser results so far (it's still difficult to find consistent time to develop specific skills). Actually in some ways, your story seems similar to mine. I didn't start to steadily improve until after I had good results with meditation and learning to keep my circadian rhythm in check.
Email me; I'd love to compare notes and also pick your brain.
