Ready is nebulous. It’s a sliding scale. There’s no upper limit to readiness, and there’s no lower limit either. You are ready when you decide you are—and this is often when the pain of your current situation or the pull of a potential one outweigh the fear of failure, embarrassment or shame.
Confidence is not a requirement for acting, it’s the result of acting. We get confidence in the doing, not in the planning. Because we’re very rarely ready to be ready, and so we’re ready when we aren’t. When we take the plunge, when we put one foot in front of the other, whilst not knowing where we’re going, when we confidently step into our lack of confidence and trust as Rumi put it that “as you start to walk on the way, the way appears.”
