It's a funny profession because there are many people with the talent and commitment to craft, who just never get that "lucky break." Sometimes, the camera doesn't love them. Other times, maybe a casting director doesn't choose them because he or she doesn't like their name or their hair color or who knows what. There are many failed actors who become (for example) lawyers, teachers, real estate agents, and bartenders, and who could have been Margot Robbie or Ryan Gosling but it just didn't happen for them.
