I can, therefore I am.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

If you think you can do it, you can.

If you can dream it, you can do it.

Begin to be now what you will be hereafter.

Be kind whenever possible. It is always possible.

Either you run the day or the day runs you.

Be gentle to all and stern with yourself.
