Don't get over-impressed by the people who seem to be doing absurdly well getting tons of kills early on and try to mimic what they're doing. They're actually not playing all that well and hyper-aggressive playstyles don't work once you start facing people who have some clue of what they're doing. Play a bunch of custom games to learn how to CS (get the last hit on minions for gold) Don't buy too many champions, save and only buy the ones you really like

Are you on EUW or NA? You could add some people.

EUW.

Thanks for all the tips. I'll actually try to play it later.
