1...never be unprepared when setting out to walk a long ways. My thighskin is painful now, and my feet hurt really bad.
2...never run your car out of oil. I did and now instead of a $40.00 oil change, I now have a $1500.00 repair
3...never run your vehicle out of gas, unless you like to walk, and then see number 1
4...never be rude to your boss...unless you like a smaller paycheck, which results in less money for gas, henceforth see number 1
5...never forget that life can be a vicious bitch when you are unprepared, short sighted, short handed, short tempered, and generally just being a douche.
