If you think you can do it, you can.

I can, therefore I am.

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

Be gentle to all and stern with yourself.

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

It's always too early to quit.

Well done is better than well said.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.
