What does the story of Franklin buying a whistle tell us?

In Franklin's article Whistle, there is such a sentence: "In short, I think the great human suffering they suffered was caused by their wrong evaluation of the value of things, and they all paid too high a price for their whistles." So I began with this sentence: this time I practiced "I paid too much for the whistle." We are all ordinary people and enjoy life. Our naked, lazy, idle and even self-deceiving and whimsical unconscious thinking always dominates our actions. I saw a short message the day before yesterday: "20-year-old people think beauty is the best, 30-year-old people think youth is the best, 40-year-old people think being an official is the best, 50-year-old people think money is the best, 60-year-old people think health is the best, and 80-year-old people don't have to care too much about their lives. Ugly people are handsome and pleasing to the eye, old people are not very healthy, and poor people are rich and kind. Who is right in this life? Life is like a big drama, which shows the ups and downs of our life. Living in the present, on the road, we inevitably have too many disappointments, only we face them and can't get through them.
