There is a quirk in memory that might be linked to this, many times if I’m thinking of something and trying to remember something you’ll draw a blank. But if you disengage in that effort sometimes what you were after will just come up out of nowhere.
It’s related to association and how the brain makes connections. If you go down one fork in the path you’re limited to what it’s associated to or connected to. If you pull out or step back your brain can then go down the right path.
Often if I just stop trying to remember and do something else, many times that acually works. It’s like a reseting or going back to the starting line for another go.
Adding new sensations to repetitive skill practice is a legit way to increase your abilities, tho tbh I’m often to lazy and like sitting in the same position doing the same stuff over n over.
I think another think to keep in mind is it may not be lack of chemistry to adapt. Chemistry is a by product of activity. There are many studys showing depression is not chemical but environmental. I think what happens is around your mid 20’s you’ve seen most of life, adapted to it to reach equilibrium. And that is what stops the adaptation. If you spend an hour in a vr game as a new user you’ll feel how adaptive you still are, but we don’t have much to adapt to as adults.
People will immerse themselves in a new language by acually going to a country that only speaks that language. And in guitar we’ll warm up, putting physical activity to stimulate our body to preform better, and increasing the chemicals related to physical movement. It’s all about the environment and risk.vs reward. And why almost everyone whos “made it” had the environment to support them.
If you want to improve you have to change your environment. Be that a gym, school, friends family etc… Or even just balancing on one leg. Same thing.
