Dang, what a mess this thread. Anyway, the first one is to never speak of what one does not know. I always get into trouble when I open my fat stupid mouth.

So always think twice before speaking, and if so, speak wisely.

The other one, tho related, is to never lose your temper. Never ever. This can get you in so much trouble that it is basically suicidal.

The satisfaction of a little rage is never worth the cost.
