Chosen -
Thank you for your service to our country. It's an honor to have you join us.
I like your attitude about the timing of your quit. It's real easy to rationalize putting it off because of the stress of life. While I can't imagine the stress someone in your position is under, I do know that everyone has problems in life. None of them should be used as an excuse to continue to poison your body.
Discipline, honor and hard work -- all things you know a lot about -- are what will make you successful here. Post roll, honor your promise, and repeat. Simple, but not easy - but then again, nothing in life that's worth anything, is easy.
