From Best of Craiglist.
There are two types of trouble . . .one is the trouble you knowingly walk into, the other is trouble that just happens . . . it's important to know the difference.
Walk softly but carry a big stick.
If you have to use said stick, make sure who you use it on, doesn't get up.
. . .
If you don't know something, go to the library and learn it.
The phrases "I don't know", "I forgot", or "I tried (and failed)" are excuses.
There is a difference between an excuse and a reason, know the difference.
