"Being a doctor or lawyer is more challenging, but Broadway performer is right up there."
Um, sorry, not it isn't. Raised in a family of theatre professionals and medical professionals. Having somebody's life in your hands and performing, say, an organ transplant as my father has, is MUCH more difficult than being a Broadway performer. To even compare them is an insult. Expecting someone to hit their turns is a lot less pressure than expecting someone to save a life.
"Get mad, then get over it." - Colin Powell
