Seneca the Younger

“Expecting is the greatest impediment to living. In anticipation of tomorrow, it loses today.”

“There will always be causes for anxiety, whether due to prosperity or to wretchedness. Life will be driven on through a succession of preoccupations: we shall always long for leisure, but never enjoy it.”

“Non est ad astra mollis e terris via.”

“Love of bustle is not industry.”

“If a man knows not to which port he sails, no wind is favorable.”
