You'll get an awakening when you get to Boot. No more pansy time. No more "you time". You train,eat, and sleep for 3 months straight, just for Boot. Your outlook on life will change.
Get in the best shape of your life. You'll still come out stronger. You'll learn to think critically when you can hardly stand or stay awake.
But hey. It's the most fun you'll ever have in your life!!
