I'm going to tell you the truth about ELO
I've been noticing something, and that is that people do not understand what works for some people may not work for others in elo. Please don't down vote me unless you truly read everything.
First of all, getting pissed and yelling at your team mates doesn't actually make your team do worse. A lot of the times, it actually makes them play better, especially in low elo, where everyone has low apm, and is playing "for fun". Being a bully to both your own team and the enemy team will gain you respect. This seriously will help you climb.
Secondly, you should be really pumped when you play this game. I recommend having a testosterone supplement if you want to play well. Caffeine also works for me. I know several diamond players who do very well, and are extremely angry people. This is because they have extremely high test, I can assure you. I can not emphasize enough how important it is to have adrenaline and test while u play. I notice I do very well when I purposely do not masturbate or have sex, and when I am on some kind of drug which gives me energy, such as heavy doses of caffeine. Lastly, I recommend finding something that makes you very angry, and using it to your advantage while you play. For me, it is probably that I am ugly and don't have a lot of money. When I think about these things while I play, I generally do very well, because it hardens my resolve while I play.
Anyways, I hope this helps some players. I find that this helps me. If you find yourself losing a lot, even though you play smart, this could be your problem.
