It pretty much boils down to how you choose to react when things go bad and you feel that "trigger". For me I think it's important to keep in mind that everyone has bad games, myself included. Recall some games where you hadn't lived up to your own standards and some of the harsh criticism you may have suffered from other players as a result. Decide whether you wish to perpetuate that cycle or if you'd rather go by the old saying of treating others the way you wish to be treated. When you feel that switch inside of you go off, think carefully before you commit it to text.
