"We speak but once. Do not repeat your questions. What is not understood or is unheard is lost to Earth. You may find new ways of understanding and ascent, but by new steps. Therefore be alert. Tiredness is not dangerous. But levity and callousness are banes to mankind. Like a householder in constant action, be not afraid of a few drops of labor’s perspiration. Even a misguided action is better than passivity. Attain the port. For each one is a ship provided. (292)"
