If you think you can do it, you can.

I can, therefore I am.

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

It's always too early to quit.

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

Problems are not stop signs, they are guidelines.

Always desire to learn something useful.

Begin to be now what you will be hereafter.

If you're going through hell, keep going.
