“...there are no shortcuts to excellence. Developing real expertise, figuring out really hard problems, it all takes time―longer than most people imagine....you've got to apply those skills and produce goods or services that are valuable to people....Grit is about working on something you care about so much that you're willing to stay loyal to it...it's doing what you love, but not just falling in love―staying in love.”
I could not have said it better myself. :-)
1) Grit is like a muscle, the more you train it, the stronger it gets. No one is born with it and everyone can develop it.
2) Grit is the combination of passion and perseverance. You need both in order to succeed in life.
3) Talent is overrated. Many people with great talents achieve little to nothing unless they are able to work hard and with persistence.
READ IF: You have long-term projects or goals in your life that challenge you and test your determination and perseverance.
