Terry Gross said this quote

I also often ask my guests about what they consider to be their invisible weaknesses and shortcomings. I do this because these are the characteristics that define us no less than our strengths. What we feel sets us apart from other people is often the thing that shapes us as individuals. This may be especially true of writers and actors, many of whom first started to develop their observational skills as a result of being sidelined from typical childhood or adolescent activities because of an infirmity or a feeling of not fitting in. Or so I’ve come to believe from talking to so many writers and actors over the years.
