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

Know or listen to those who know.

What you do today can improve all your tomorrows.

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

It's always too early to quit.

You never know what motivates you.

Be gentle to all and stern with yourself.

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

Be kind whenever possible. It is always possible.
