Well done is better than well said.

It's always too early to quit.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.

Problems are not stop signs, they are guidelines.

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

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

Things do not happen. Things are made to happen.

Know or listen to those who know.
