I've never boxed in my life, never been in a military base in my life, never grew up with anyone in the military.
There are many things in your heart you can never tell to another person. They are you, your private joys and sorrows, and you can never tell them. You cheapen yourself, the inside of yourself, when you tell them.
For me, I just try to make sure I eat enough and drink enough water and that's about it.
