While some people make it big without any experience, I do feel talent is a requirement of being successful. It is an incredibly competitive and tough business. When my kids were younger I spent time on the Backstage forums and there was a woman who spent a lot of her time generously advising people on how to break into the business. She didn’t start even start until she was 42 and had an amazing career as an actress until she died at 72 (She won 2 Emmys!). Now she did not do MT but she taught me that with hard work (and talent- as she was incredibly talented) anything is possible, and it is never too late to reinvent yourself. You may not know her name but if you google Kathryn Joosten you will definitely recognize her face.
