"Every hero becomes a bore at last"

This quote by Ralph Waldo Emerson is a suggestion that even the most brave of people can end up being tiresome and dull in time. It recommends that no matter how excellent a person is, they will ultimately end up being predictable and uninteresting. This might be due to the fact that they have been around for a long time and have actually ended up being too familiar, or that they have actually ended up being too comfy in their own success and have stopped pressing themselves to be much better. It is a reminder that even the most inspiring of people can become mundane and boring if they do not continue to challenge themselves and pursue greatness. It is a cautioning to not take anyone for approved and to constantly aim to be the very best variation of ourselves.
