The fear of death? Fear of pain? Having children, husbands, wives etc? It's not always immediately obvious what is holding us back. I found it heartening to realise that part of it for me is fear of failure. I just thought it was fear of pain. There's more I can do about fear of failure so that was a positive realisation for me. How about you? Also, have you also realised you had fears you didn't think you had?
