I can, therefore I am.

Be gentle to all and stern with yourself.

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

It's always too early to quit.

Begin to be now what you will be hereafter.

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

If you can dream it, you can do it.

Problems are not stop signs, they are guidelines.

If you're going through hell, keep going.
