I can, therefore I am.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

Quality is not an act, it is a habit.

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

If you've got a talent, protect it.

Things do not happen. Things are made to happen.

Either you run the day or the day runs you.

Be gentle to all and stern with yourself.
