“It is impossible to enjoy idling thoroughly unless one has plenty of work to do.”
-Jerome K. Jerome

"A goat owned in common always starves."
-West African proverb

There is usually only a limited amount of damage that can be done by dull or stupid people. For creating a truly monumental disaster, you need people with high IQs:

* They may believe that learning about something is the same as doing it
* They can be really good at coming up with excuses for failure
* They sometimes become overconfident about their intellect
* They're used to being right so much that they stop listening to other people
* They may try to show how "uncommon" they are

 -Thomas Sowell

Only a mediocre person is always at his best.

-Somerset Maugham
