First the definition:
“The ability to work hard and respond resiliently to failure and adversity; the inner quality that enables individuals to work hard and stick to their long-term passions and goals.”
Now the word:
The definition of grit almost perfectly describes qualities every successful person possesses, because mental toughness builds the foundations for long-term success.
For example, successful people are great at delaying gratification. Successful people are great at withstanding temptation. Successful people are great at overcoming fear in order to do what they need to do. (Of course, that doesn’t mean they aren’t scared — that does mean they’re brave. Big difference.) Successful people don’t just prioritize: They consistently keep doing what they have decided is most important.
All those qualities require mental strength and toughness — so it’s no coincidence those are some of the qualities of remarkably successful people.
