When I’m unhappy, I feel like I’m doing life wrong. I’d rather be happy. But is happiness the point of life, or is there more to it? If I pursue happiness, mine first then for those around me, is that selfish? But if there’s a bigger purpose, then what about people with Alzheimer’s or dementia who can’t recall recent experiences or make plans?
The purpose of human life is to continue the species. Everything else is a detail.
Many people look for meaning, which varies wildly from person to person. I don't consider it wise to try to find One True Meaning, but instead to connect with what you consider meaningful.
