When you grow up, son, never ever go to bed at night knowing that there was something you could have done during the day to strike a blow against injustice and you didn’t do it.

Never lie in bed at night asking yourself questions you can't answer.

Anything that can’t be done in bed isn’t worth doing at all.

Do what I will never do.

Never do anything when you are in a temper, for you will do everything wrong.

If you stop to consider the ramifications, you’ll never do anything.

Don't try to solve serious matters in the middle of the night.

The worst thing in the world is to try to sleep and not to.

never stand up when you can sit down, and never sit down when you can lie down.

It is never worth while to do anything by halves.

Never take counsel of your fears.

If people never did silly things nothing intelligent would ever get done.

When in doubt, my dear fellow, do nothing.

The one path that never works is the most common one: doing nothing at all.
