"You write, “If you want to be happy, think like an older person.” Can you explain how that works?
We know from a lot of research that older people are more content with their lives than younger people are. Thinking like an older person is thinking about resilience and focusing on what is as opposed to what is not. Accepting your mortality by not being so afraid of it. When you are older, you view the time horizons in front of you differently. You understand the days are finite, and we might as well enjoy the ones we have left. The big lesson for me, the really practical one, is waking up in the morning and saying, “Thank God for another day.” It’s the conscious practice of gratitude."
