When Ginna Claire Mason was 13 years old, she saw the Broadway show “Wicked” for the first time and was enchanted. At intermission of that performance, the Nashville teen-ager told her parents, “I’m going to be Glinda someday.” Something like 15 years later, Mason is doing exactly that. She’s the actress currently playing Glinda in the Broadway production at the Gershwin Theatre in New York City. Most of us have crazy ideas about what we’re going to do with our lives when we’re 13. For many of us, those ideas evolve or even radically change over time, but a few people hold onto dreams about what they truly want to do. Most people give up on their dreams and that’s understandable. Some dreams aren’t possible. But it’s a mistake to believe that nobody can do the work he loves. Few of us are lucky enough to do that, but some who have the talent and the determination do that. It’s worth remembering that dreams can come true. At least sometimes.
