You're not just going out there, maybe sacrificing your own life. There's also sacrifices still going on at home. You can serve in the military and have a good marriage, but you just need to be aware of it so you can take those steps to take care of it.
Friends, companions, lovers, are those who treat us in terms of our unlimited worth to ourselves. They are closest to us who best understand what life means to us, who feel for us as we feel for ourselves, who are bound to us in triumph and disaster, who break the spell of our loneliness.
