Be gentle to all and stern with yourself.

It's always too early to quit.

What you do today can improve all your tomorrows.

Problems are not stop signs, they are guidelines.

If you're going through hell, keep going.

Know or listen to those who know.

You never know what motivates you.

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

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