Aristotle
"Knowing yourself is the beginning of all wisdom.""It is the mark of an educated mind to be able to entertain a thought without accepting it.""No great mind has ever existed without a touch of madness.""Anybody can become angry — that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way — that is not within everybody's power and is not easy.""Excellence is never an accident. It is always the result of high intention, sincere effort, and intelligent execution; it represents the wise choice of many alternatives - choice, not chance, determines your destiny.""A friend to all is a friend to none.""I count him braver who overcomes his desires than him who conquers his enemies, for the hardest victory is over self.""Pleasure in the job puts perfection in the work.""To write well, express yourself like the common people, but think like a wise man.""The more you know, the more you know you don't know.""It is during our darkest moments that we must focus to see the light.""He who cannot be a good follower cannot be a good leader."
