>>12183089it could be an adhd thing, not that you suffer from the disorder, but in the sense that society suffers with all these distractions and there's so much to do, so many shows to watch, social medias to check up on, opinions to hear, etc..
the peak on B should be lower than the peak on A, it seems you're burning out the passion you have for thing too soon. if you find yourself getting really excited about it, try to temper your feelings, relax, and breathe. maybe take a break from thing and force yourself to work on thing2 for a bit. or just read something random, watch a movie, anything else.
and generally try to not give in to the infinite scrolling world we live in. watch an old movie without picking up your cell, go for a walk and inspect an ant colony, draw a space battle, close your eyes and listen to music, play comfy game. just do stuff you like but do it slow.
