Without hard work, nothing grows but weeds.

What you do today can improve all your tomorrows.

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

Things do not happen. Things are made to happen.

By failing to prepare, you are preparing to fail.

Well done is better than well said.

Know or listen to those who know.

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

It's always too early to quit.
