What you do today can improve all your tomorrows.
Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
Always desire to learn something useful.
They should hold themselves absolutely upon the immovable foundation of truth and nature, whereby alone they can save themselves from misapprehensions and from the danger of being entirely carried away from reality into mere dreams and fictions.
