Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

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

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

It's always too early to quit.

Know or listen to those who know.

Either you run the day or the day runs you.
