Everyone who has reached adulthood was once a child. The current president was once a young man.
We have no way of knowing what opportunities await young people as they mature. We have always been disappointed when we attempted to predict the future via the lens of history. Every guy who was once youthful is given the opportunity to demonstrate that he is deserving of greatness.
Everyone will have one thing in common: they were all once young. As a result, being young is deserving of praise and admiration.
