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.
The trick with computers I think is to approach old and new things with the same reverence as you would like your favourite chair and not be seduced by the constant innovation otherwise you never do anything.
