Manage what you can manage, the rest can fukk off.
It's going to get to a point where it's going to be REALLY every man for himself so it's best to start getting used to using cold logic and executing quick decisions regardless of however painful those choices may be.
To act or not to act, that's the core of a soldier's mentality. Everything else is filler outside of the facts needed to execute your prerogatives..your emotions be damned in these perilous times, if I feel as though you're a threat to my survival..I will attempt to destroy you and all of your company without mercy and with extreme prejudice.
