Annie and Nomercy you two put it so well!!!! A few hints to dissipate the “Buck fever”.
Try to situate your stand so you have shooting lanes in and area where once you see a deer he is ready to shoot at in a few seconds. 9 out of ten deer I shoot are dead 5 to 20 seconds after I see them.

Don’t stare at the deer, as soon as you see him move your attention to the scope at the likely shooting spot, just peep over the scope to see where the deer is moving and back to the scope at the shooting spot. DO not follow the deer through no shoot areas checking him out. Concentrate on the shooting spot. Deer don’t vanish even though it seems so some times and if he does when in a no shot area it really doesn’t matter anyway.

Like nomercy said a few under the belt helps so if you must go on a fixed hunt probably expensive but get a good rack on the wall.
