When we forge our own path, there will be mistakes, setbacks, and challenges. They are part of life's journey, and I don't know anyone who hasn't experienced them. Even if we're not successful on a path we take, it's the path we chose. That means we must accept responsibility for it, and the lessons are ours to learn. Is there the possibility of hearing, "I told you so", and "Oh, well", if the path we take turns out to be a bad one? Absolutely. And is it possible we'll need help? Yes. But it's important to bear in mind that just like we chose one path, we can choose another. It may not be easy, but we shouldn't allow that to deter us. If we want to accomplish something, we should take as many paths as necessary to get there. Many successful people experienced some of their greatest successes after suffering disappointments and defeats on a path they chose. They succeeded because they stayed focused on their end game, and changed or corrected their course as necessary to get there.
In my own life, I've found it's easier to swallow the bitter pill of mistakes, challenges, and setbacks when I'm minding my own business--that is, forging my own path. Truth be told, those who may offer opinions have been there themselves.
