Quote by Ralph Waldo Emerson
What I must do is all that concerns me. This rule, equally arduous in actual and intellectual life, may serve for the whole distinction between greatness and meanness. It is harder because you will always find those who think they know what is your duty better than you know it.
Summary
This quote by Ralph Waldo Emerson highlights the importance of focusing on one's own obligations and responsibilities. According to Emerson, one should prioritize their own duties and tasks above all else, both in practical and mental aspects of life. This principle acts as a criteria to differentiate greatness from mediocrity. The rule is challenging because there will always be individuals who believe they understand one's duties better than themselves. Therefore, Emerson suggests that staying committed to one's genuine responsibilities is key to personal growth and achieving greatness.
