I'm too good for this game.

And since I'm really not, I ask you (some of you must have an EUW account - no?) to be my master. Introduce me to this game, please. I'm Silver 4 but somehow I feel like I'm wood 7. Seriously, I care too much about this game I feel I can't let go. At least, can someone of you have a game with me and tell me WHAT are my mistakes? I don't know, I can't take the step forward to become better.
