I can, therefore I am.

Things do not happen. Things are made to happen.

Always desire to learn something useful.

Do not weep do not wax indignant. Understand.

Be gentle to all and stern with yourself.

You never know what motivates you.

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

Without hard work, nothing grows but weeds.

Begin to be now what you will be hereafter.
