I once heard that Mr. Ivica Osim, when he was serving as the head coach of the Japanese national football team, used to say to the players "Run, run, and run!".
Once, a player complained that his legs were aching. He could not run due to the pain. Mr. Osim then famously said: "Think of a wild rabbit. Would the rabbit ask the fox to wait, because one of his legs was aching?"
Mr. Osim's words were apparently a paraphrase of Vladimir Lenin, who once remarked that it was important to "leran, learn, and learn".
Sturm und Drang. These are words of passion. I sometimes come back to these words in my difficult times.
