It's always too early to quit.

Without hard work, nothing grows but weeds.

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

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

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

Know or listen to those who know.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.
