Well, my mother just told me that I have ADHD.
No clue why she just took until now to tell me, that would totally explain my hyperactivity and concentration issues.
Mother didn't tell me until now because It wasn't much of a problem during high school, mostly a problem in primary school.
How do I concentrate better? I find it a huge obstacle in my life?
This would explain why caffeine helps me concentrate, while other peoples will have troubles concentrating with caffeine, hmm this is interesting.
Since I'm doing uni have to be able to concentrate as much as possible.
