Most people stop right on the verge of success. Many times, we are right on the cusp of getting where we want to be and we just stop, which is why we need to cultivate grit.
In order to build in us that don't quit mentality, we first need to realize that we're playing the long game. We need to realize that the things we're striving for are not a sprint, they're a marathon. We need to celebrate progress along the way, but know we're in this for the journey.
