Is there an invisible force keeping you from taking risks and venturing into the unknown? For many of us who have become accustomed to being comfortable, the answer is “yes.” Bethany Butzer, Ph.D., writes about the “invisible shackles” that are mostly in our heads. Our comfort zones become so easy and known, even when there’s stress and suffering involved, that it’s difficult to change. We live in a state of “learned helplessness,” where we erroneously believe there’s nothing to be done and we have no control. Butzer suggests redefining success and getting rid of the self-limiting beliefs we live by.
