Congratulations on your new Marine. With the way the United States has become it is a hell of testimony to her and her family. I know both of you are very proud as you should be. I have been separated for quite a few years now but still miss it.
I still remember the instruction from our drill instructor at the rifle range. He preached and drilled into me and the others the acronym BRASS

Breath
Relax
Aim
Sight
Squeeze

This still serves me well today.
