Translate, study, read — time wasted. Walk, contemplate, meditate, create!I added a comma after Traducir (there's a comma in the index on p. cxxxix). I wasted my time translating this, and you're wasting your time reading it.
Traducir, estudiar, leer: Tiempo perdido. ¡Pasear, contemplar, meditar, crear!
