"You have to love what you do. Without passion, great success is hard to come by. An entrepreneur will have tough times if he or she isn't passionate about what they're doing. People who love what they're doing don't give up. It's never even a consideration. It's a pretty simple formula."

There must be no division by class hatred, whether this hatred be that of creed against creed, nationality against nationality, section against section, or men of one social or industrial condition against men of another social and industrial condition. We must ever judge each individual on his own conduct and merits, and not on his membership in any class, whether that class be based on theological, social, or industrial considerations.

— Theodore Roosevelt
