Fear of Success
“We are all familiar with the idea of fear of failure. It is what keeps many of us from taking risks, preferring instead to stay within our comfort zone. No less real, though, is fear of success. We want to succeed: so we tell ourselves and others. But often unconsciously we fear what success may bring: new responsibilities, expectations on the part of others that we may find hard to fulfil, and so on. So we fail to become what we might have become had someone given us faith in ourselves.”
