I have this problem since I was a kid, I am good at learning and solving problems but I can never concentrate long enough to learn deeply about one subject or to solve a problem efficiently or to optimize the solution and this is taking a big hit on pursuit of my academic degree.
After I do sport or watch a movie, youtube, listen to a song, eat food that I like etc. basically anything that makes me happy I get this feeling of happines in my chest that I cannot explain and there is a storm going on in my mind it feels like I am thinking about 100 stuff at the same time and I also start to remember some of embarrassing things that happend like 15 years ago ,10 years ago and while I am remembering this stuff it feels like I am having 100 of thoughts but I really am not thinking about anything.
While in this state I am not even able to concentrate on youtube or a movie or a song, I listen to it like 20-30 seconds and than I have to change it because it starts to get boring same with youtube video or movie.
Reading or learning in this state is impossible. I have to wait for like 5-6 hours to calm down or maybe even a day until i can calm down and do something, this is very problematic.
This effect is most powerfull after sport or physical labour
If anyone knows anything or has any Idea, please help
