Working on yourself to make yourself a better person is what true nobility is. Said best by Ernest Hemingway, “There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self.”
Stop focusing on others and their accomplishments and focus on yourself, work on making yourself a more superior version of the person you were yesterday. All small improvements you make will add up and compound, and keep compounding. Until you achieve everything you want and become exactly the person you want to be.
