#5 Do Not Brag

If you do well, do not brag.  If you lose, do not show anger.  Instead say something like. "That was fun!" or "Great game." or say nothing at all.  Bragging about yourself can put you in a negative light.  There is no need to put your accomplishments or abilities on display.  Have you every liked a professional player because you've watched him improve?  Suddenly, he begins to brag about his accomplishments and then just as suddenly, you no longer have the enthusiasm about him you did when he was just a regular guy doing well.  Don't let this happen to you.  We are all good at something and do poorly at other things.  And i also believe if you can learn something, so can someone else.  No one stays on top for ever.  There should be plenty of room to share the lime light.  Let your accomplishments speak for themselves.
