i agree with the posts so far, and would like to add that shooting before you head to the stand can build confidence greatly. Your shooting cannot slip when the season starts. you are walking through briars, banging equipment around and things can get out of whack.I like to take even just 5 minutes to shoot at 20, 30 and 40 yards with my broadheads before every other, if not every, hunt. not only does this reassure you that your equipment is still functioning properly and is sighted properly, but it adds a great deal of confidence when you head for the tree knowing that you are "dead on" and telling yourself that if that animal comes within YOUR effective range (must be set by you and no one else), you can make an ethical shot and humane kill.

I find that a somewhat "cocky" attitude adds confidence and isn't always a bad thing in bowhunting as long as it is contained and isn't reckless. I like to reassure myself that i WILL kill any animal that comes in range. in telling myself this, for self affirmation, i concentrate twice as hard when the animal finally does give me that shot i have been waiting for. I am not openly cocky, a jerk or "mouth" to anyone, it is contained, and i don't think i am better than anyone else, i simply use this as a motivator for myself, that i WILL make my hunt end in success if i get the chance.

just some of the things i do to stay confident in my abilities, good luck and keep your head up and get after 'em!
