Trying to approve demeanor on the floor.

Sounds to me that its how you carry yourself, your court presence. I don't think you have to talk to players to change it. I would video tape yourself, try to let loose a little more on the floor, sounds like you're really tense out there. Video tape is the only wa yyou'll be able to see the problem. It will make it much easier to try to fix.
