To know oneself, one should assert oneself.
After a storm comes a calm.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
Who seeks shall find.
Do not weep do not wax indignant. Understand.
Problems are not stop signs, they are guidelines.
Know or listen to those who know.
Always desire to learn something useful.
God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.
Science already contained all that was necessary, if you just brought it out.
