You never know what motivates you.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
I can, therefore I am.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
No true and permanent fame can be founded except in labors which promote the happiness of mankind.
