This might seem obvious, but you'd be surprised at the number of bowhunters I talk to who don't shoot their bows DURING the season.......[:-]
Now is when we should be practicing constantly, even if it is just flinging a few arrows at a bag target as you head out the door.
Keep the muscles, reflexes and form in tip top shape.......It will also alert you to any changes in your gear.
Keep the confidence level in your shooting high! Don't be the guy on November 1st who has a tight 25 yard shot at the buck of a lifetime, but hasn't PRACTICED that shot since September.
Good luck and shoot straight!
