Practice exercising on about 2 hours of sleep per night. Practice eating a meal in 90 seconds. Practice taking your ASVAB on 1 hours sleep. Choose 2-3 people to call when they give you phone time. Say hi, talk about them, don't talk about what you are doing. Also practice memorization. Memorize your local government, Commissioner, District Attorney, Mayor, City Manager, Sheriff, Constable, Treasurer, etc. You'll have to memorize lots of names and ranks when you get there. If you get in the habit of doing that now it will make it a lot easier when you are having boots thrown at you for not having you lock box in order at 2am with 4 NCO's yelling through your skull.
