Last week one of my clients launched her first e-course.
About 72 hours before the first launch, we were on the phone and she asked me, "When did you know you were an expert?"
I had to take a moment to think about it, and I realized that the feeling of "expert" never really comes.
I easily have the 10,000 hours under my belt (also the bad eyesight that comes with staring at paper/computer screens for that long), I have my degree in writing (and the loans to prove it), and I my adult career is as a writer.
