It's always too early to quit.

Begin to be now what you will be hereafter.

What you do today can improve all your tomorrows.

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

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

Who seeks shall find.

Things do not happen. Things are made to happen.

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