If there is a subject that catches my attention I tend to want to know everything about it and I'll begin researching it online, but become frustrated not understanding which aspects I should study first. It's not a matter of finding the information, but a matter of me becoming angry because I can't sort out how it should be perfectly organized in order to be studied perfectly (I do other weird things with organization too). This usually leads to me not even learning much about the things I want to learn or do/become successful at and laying in bed just thinking about it and getting nowhere. It really ruins it for me.
I like competitive games, recently I started playing chess and while I've been learning things online in order to understand more about the game and improve, I have tried to keep myself from falling into my past habits. I also play a fighting game that I practice religiously and study for hours each day and I've been trying to break my obsessive habits in order to improve. I really enjoy learning about competition and theory based things in games - especially the ones I like such as: fighting games, chess, card games, speed solving rubik's cubes. But obsessing over organization of thoughts, finding the path to be the best at one of these things, perfecting each and every part of activity and learning everything about it overwhelms me at times and frustrates me to the point that I become tired and quit or never follow up on things. I also do this same thing with music. I enjoy composing music, and rarely finish or even start pieces due to this behavior.
