1. Be calm.Start by removing emotion when making a decision, as we are all human, then reintroduce that ecision.
2. Competition is healthy and the game should be played in great spirit and respect.
3. Be driven by how great you can be and know what you want and say.
4. Don't be too serious..... all the time. Enjoy what you are doing, and enyoy others company.
These are my four things that I keep in mind and you will find your own. Watch others around you and be successful and happy, and if there is someone who is awesome follow them closely. People will be time generous, considering and usually be very much in charge of themselves.
