My brain is my biggest obstacle!

Arekkusu has finished his highschool and applied for a university. He has a lot of hobbies and future business plans and he did put a thought into everything. Yet he can't take an action! He can't even decide where to begin!
Lately he lived through a breakup with his girlfriend. Why she treated him like this? Arekkusu began to investigate the topic of how his brain works, by watching an internet streamer who claims to be a qualified psychiatrist. What did he find out and will he manage to achieve his goals?
