Be gentle to all and stern with yourself.

I can, therefore I am.

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

Know or listen to those who know.

What you do today can improve all your tomorrows.

Go for it now. The future is promised to no one.

It's always too early to quit.

Either you run the day or the day runs you.

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