4 functioning brain cells, able to give up your private life, a lazy left foot so you can lay it on the clutch pedal while driving so the clutch gets good and worn, a 20 ft cable that you can wire into your wiper motor so you can power your radio, the ability to rub every curb while making right hand turns, having a good cell phone so when you over heat the motor and blow it up you can call the shop and say "I don't know what happened it was fine 5 minutes ago" or having a cell phone while broke down and refusing to give your # to your sup and then making the mechanic use mapquest to find your dumb
. And last but not least, driving the truck with the brakes grinding for 5 days and then on your way out in the morning stop by the shop and try to blame the night guy for not fixing it without you writing it up!!!! If you can do all of the above you'll be just fine.......
