Strive Wisely

"It is exercise alone that supports the spirit, and keeps the mind in vigor."
-  Cicero, 65 BCE

"So many older people, they just sit around all day long and they don't get any exercise. Their muscles atrophy, and they lose their strength, their energy and vitality by inactivity."
-  Jack LaLanne

"Vigor (viriya) is the state of a hero (vira). Its characteristic is exertion. Its function is to support or consolidate related mental qualities. It is manifested as non-collapse. Because of the saying, "Stirred, one strives wisely," its proximate cause is what stirs the heart. When initiated properly, it should be seen as the root of all attainments."
-  Visuddhimagga XIV, 137, A Buddhist Scripture 

"The chief condition on which, life, health and vigor depend on, is action.  It is by action that an organism develops its faculties, increases its energy, and attains the fulfillment of its destiny."
-   Pierre Joseph Proudhon
