Most people quite after the first round of frustration and defeat. That’s why “most people” are apart of the majority. Simple as that. You NEED to push back harder, remember why you STARTED, and execute on that. The frustration and defeat you’re feeling means you are close to a breakthrough and an elevation from the plateau. It’s so hard because you’re entering a realm not many people have experienced because NOT MANY people have what it takes to push against the frustration to get there!
