How to get out of silver?

1) "/mute all" in chat.
2) Don't do random builds (You can always look for champion builds on the internet).
3) Get good at your main champions. (Learn combos etc.)
4) Learn from your mistakes (i.e When you die try to figure out why you died and try to avoid it next time).
5) If you start to rage then take a few hour break (Playing while angry will get you nowhere).
6) Try to outplay your opponents (If they seem to do the same thing over and over again then try to avoid it and kill them at the same time).
7) [Optional] Watch pro games and see what they do (You can always learn from pro players).
