how can you practice for the monent of truth? like having to hold your bow at ready for 15 minutes without moving while you have a gobbler at 30 yards and closing. unlike deer hunting were things happen a little faster usually.

The best practice I know of (for putting pressure on yourself) is 3D (other than being in the moment).

The more we put ourselves "in the arena", though, the better we prepare ourselves for that time.

IMHO, there is NO substitute for actually putting an animal on the ground.  None.  Passing on them is all fine and dandy, but you could build a city in between letting one walk and putting that deer on the ground.
