Tell me about your understanding of the topic "Stepping stairs into the piano"

It means, be optimistic about life, stairs? Just like the suffering of life, is it bitter when you climb higher and higher? The more difficulties there are, the less suffering there will be? At the end of the day, but when you treat the stairs as steel? When you play the piano, you also learn to take pleasure in pain. As another kind of fun, as boring? Life condiment
