When is the right time to tell your CEO story?

Some might say that a CEO can’t tell their story until after they’ve reached success? Which by all means is true, there has to be some kind of success to even become a CEO after all. However ‘success’ as a benchmark for when to tell isn’t very helpful, because who decides what success really looks like. When do you call yourself a success? Surely that marker is different for everyone, and from what I’ve seen is often used far too late.
