Your LoL Credo

What set of personal guidelines do you set yourself when playing a game of League?

Mine are:

Team Player Guidelines

1. Mute flamers/trolls.
2. Don't get in the middle of an argument.
3. Offer encouraging words to those that are struggling.
4. Compliment everyone (even enemy team) for good plays.
5. Don't focus on others' mistakes. Focus on fixing/learning from your mistakes but don't let them get to you so much that you make more.
6. Don't play angry.

Gameplay Guidelines

1. Be decisive. Even if it causes a mistake.
2. You can't save everyone. If you go back to save some people you may end up dead yourself. Just leave and cut your losses.
3. Place the most efficient wards you can.
4. Be a team player.
5. Don't rely on the jungler but don't be afraid to ask for ganks (politely).
