Mitch and Morrie talk about the meaning of life. The author writes, "Devote yourself to loving others, devote yourself to your community around you, and devote yourself to creating something that gives you purpose and meaning." This quote shows that you shouldn't be selfish. You should love other people and give your life a meaning.
Mitch and Morrie talked about why it's important to forgive yourself and others. The author writes, "'Norman and his wife moved away to Chicago... Charlotte had to get a pretty serious operation... we were very hurt because they never called to see how she was. So we dropped the relationship... I met Norman a few times and he always tried to reconcile, but I didn't accept it... I shrugged him off... a few years ago... he died of cancer. I never got to see him... It pains me now so much.'" (Albom 165) This quote shows that It's important to forgive. You don't have an unlimited amount of time to forgive someone you're mad at. If one of you passes away and you never forgave them, it'll be even harder to forgive yourself.
The flashback in chapter 9 talks about why it's important to be able to trust others. The author writes, "'... Sometimes you cannot believe what you see, you have to believe what you feel. And if you are ever going to have other people trust you, you must feel that you can trust them, too--even when you're in the dark. Even when you're falling.'" This quote shows that if someone is gonna trust you, they're gonna expect you to trust them as well.
Morrie was talking to Mitch about death. He was saying that we know we'll die, but still we just don't believe it. The author writes, "'Everyone knows they're going to die... but nobody believes it. If we did, we would do things differently.'" (Albom 81). This shows that Morrie thinks that we should believe we are gonna die at the same time as knowing.
