Happy is he who knows his follies in his youth.

A fortunate person recognizes youthful mistakes while there is still time to learn from them. Early self-knowledge can turn error or embarrassment into guidance for wiser choices later in life.

The saying values honest reflection rather than youthful perfection. It encourages people to correct poor judgment and harmful habits, but it does not excuse conduct that has caused serious harm.

Use it as reflective advice for someone who can acknowledge earlier poor judgment without treating it as permanent disgrace. It suits discussions of learning, humility, and personal growth, especially when the focus is on taking responsibility and changing course.
