Let no one be slow to seek wisdom when he is young nor weary in the search of it when he has grown old. For no age is too early or too late for the health of the soul.

What you do has far greater impact than what you say.

Experience, the interpreter between creative nature and the human race, teaches the action of nature among mortals: how under the constraint of necessity she cannot act otherwise than as reason, who steers her helm, teaches her to act.

Beauty without intelligence is like a hook without bait.

In particular I may mention Sophocles the poet, who was once asked in my presence, How do you feel about love, Sophocles? are you still capable of it? to which he replied, Hush! if you please: to my great delight I have escaped from it, and feel as if I had escaped from a frantic and savage master. I thought then, as I do now, that he spoke wisely. For unquestionably old age brings us profound repose and freedom from this and other passions.

Your energy, your spirit are important considerations. Feeling petty and frustrated can have reverberating consequences for your ability to think strategically and reach your goals.
