This is my life

In Full Metal Jacket the marines recite a creed about their rifle. It works just as well for the one thing you really have to master.

This is my life. There are others like it, but this one is mine.

My rifle is my best friend. It is my life. I must master it as I must master my life. Without me, my rifle is useless. Without my rifle, I am useless. I must fire my rifle true.

Swap the rifle for your life and read it again. This is yours. No one else gets this one. Master it, aim it true, and don’t waste a single round.
