Michael J Fox speaking at New York Comic Con 2022 said, "I am very optimistic. Optimism is about thinking that things are likely to get better than they are going to get worse. And if you believe in that, you can be grateful for it. If you are grateful for it, you will sustain optimism for the rest of your life."
“Because you don’t just receive optimism. You can’t wait for things to be great and then be grateful for that. You’ve got to behave in a way that promotes that. Still, it’s hard to explain to people how lucky I am, because I also have Parkinson’s. Some days are a struggle. Some days are more difficult than others. But the disease is this thing that’s attached to my life — it isn’t the driver.”
