I can, therefore I am.

Things do not happen. Things are made to happen.

Problems are not stop signs, they are guidelines.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

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

Either you run the day or the day runs you.

If you can dream it, you can do it.

If you're going through hell, keep going.
