Discoveries are made by not following instructions. Do the impossible and your boss will add it to your duties. Don't cloud the issue with facts. Don't let your superiors know you're superior to them. Don't question authority, it doesn't know either.
Eternal vigilance is the price of freedom.
Every job requires a tool that you don't have. From listening comes wisdom, from speaking, repentance. Give a man an inch, and he thinks he's a ruler. He who is good for making excuses, is seldom good for anything else. I can't remember if I used to know that.
