In a time of few guarantees, I have one for you. All of the successful women you have admired all have experienced self-doubt at some point in their careers – and very likely do so on a day-to-day and ongoing basis. Within the book I will be publishing in 2009, I interviewed very senior women at a range of organisations and they all had times when they were unsure about the road ahead, but didn't let that stop them from putting one foot in front of the other. At a workshop I ran on risk-taking and overcoming indecision and one of the delegates, a woman with a PhD in a scientific field, admitted quietly to the larger group that she often felt like a fraud at times. I asked the group who else felt that way and every single hand was raised – much to her relief when she cried out "I thought I was the only one". If you think success can come to you only once you are 100% sure of yourself, you will be waiting a very long time. Successful women have moments, even hours of self-doubt, but they still know that they can make the most of any situation and have the self-belief to overcome the doubt and any mistakes they make along the way. Successful people were once described beautifully to me as being "like ducks…all calm and unruffled on the surface but paddling like hell underneath it all". You may be paddling, but are you getting anywhere?
