"A man can be himself only so long as he is alone"

This quote recommends that a person can truly be their genuine self only when they remain in solitude as well as not surrounded by the impact or assumptions of others. In the existence of others, individuals might act in different ways or change their behavior to fit in or meet the assumptions of those around them. Nevertheless, when one is alone, they are totally free to be their real selves without any external stress or impact.
