When you’ll be 50, do you think you’ll like the 20-year-you who made the major decisions for your life, or do you think you would have preferred the 50-year-you to make those decisions?
This is an argument for traditionalists. Listen to your 50-year-you, aka your parents, your community seniors, etc.
But reversely, if we tilted more towards listening to the elder-you, would there be enough renewal in society? Enough happiness at 20 years old?
