Oh jeez. Each of these bullet points needs a page or two of footnotes, additions and exceptions. Let me add a few:
13) Don’t be stupid.
14) Be stubborn only when it matters. Change your mind when proven wrong.
15) In an emergency situation or a defensive position, if you are not improving your situation you are wrong.
16) Keep your perspective and do not waste your strength. “Fatigue makes cowards of us all.” - G.S. Patton
17) Contamination conquers determination, so keep it clean.
18) Murphy’s Law: “If anything can go wrong, it will, and at the worst possible time.”
19) Cheops’ rule: “Nothing is done on time or under budget.”
20) The fourth law of thermodynamics: “There is never enough of the right kind of fuel and energy.”
Amen on keeping it clean. More people died in WWI from disease than from the fight.
