Morrie embraces the little things in life such as music. He does this because he know that he will die soon so the little things in life start to matter. This relates to the talk about More is Good. Morrie believes that items don't matter in life, the little things matter like nature, music and emotions. When you are dying you realize this. You also learn than life is more than just items. Then, the phrase More is Good becomes Everything is Beautiful.

I agree with the passage from the book. When people are in need of something they do use substitutes. For example when someone leaves for an amount of time the other person tends to hang out with different people until the person comes back, this can also work for feelings and items. People do this because they miss something or are in need of it. I think people substitue because they are lonley and the item/people can comfort and distract them from the feeling/person that they miss.

Morrie believes that we are brainwashed with the phrase More is good. We are caught up with having bigger and better things that the important things in life don't matter. He says that we are hungry for love that we are willing to accept items. We were expecting the items to give us a the love we need. But the truth is that money and items are not the substitute. The substitute is people because unlike items they can give us love.
