It once occurred to a certain king that if he always knew the right time to begin everything; if he knew who were the right people to listen to, and whom to avoid; and, above all, if he always knew what was the most important thing to do, he would never fail in anything he might undertake.
And this thought having occurred to him, he had it proclaimed throughout his kingdom that he would give a great reward to anyone who would teach him what was the right time for every action, and who were the most necessary people, and how he might know what was the most important thing to do.
And learned men came to the king, but they all answered his questions differently.
In reply to the first question, some said that to know the right time for every action, one must draw up in advance a table of days, months, and years, and must live strictly according to it. Only thus, said they, could everything be done at its proper time. Others declared that it was impossible to decide beforehand the right time for every action, but that, not letting oneself be absorbed in idle pastimes, one should always attend to all that was going on, and then do what was most needful. Others, again, said that however attentive the king might be to what was going on, it was impossible for one man to decide correctly the right time for every action, but that he should have a council of wise men who would help him to fix the proper time for everything.
