In an ET interview, conducted by the actor's son, Draco Verta, whom she shares with ex-husband Mike Verta, Danica McKellar got into the ins and outs of being a child actor. When Draco asked his mom what she remembered most from the heights of "The Wonder Years," McKellar revealed, "It was a lot of going back and forth to the school trailer," referring to having to balance her job and doing schoolwork. She added that she would never push Draco into the business if he didn't want to do it himself, but that she would provide guidance if he ever expressed any desire to become an actor.

A lesser-known fact about McKellar is that the Hallmark star also has a degree in mathematics, a field she got into after "The Wonder Years" ended in order to push herself. "I needed to find out how I was valuable outside of Winnie Cooper," the actor explained, adding that she loved knowing she had value outside of her performance skills and looks.

McKellar enrolled in UCLA's math program, graduating summa cum laude, aka with the highest honors. While on HLN's "Evening Express," McKellar shared that taking on something as hard as math helped develop her self-esteem. In order to help young girls do the same, McKellar decided to start writing math-themed books, becoming a bestselling author in the process.
