Know or listen to those who know.

Be thine own palace, or the world's thy jail.

I can, therefore I am.

Things do not happen. Things are made to happen.

The wise does at once what the fool does at last.

The most effective way to do it, is to do it.

It's always too early to quit.

The dog that trots about finds a bone.

Problems are not stop signs, they are guidelines.
