I'm sure there are many people who wish they could do something else for a living. I also have a feeling more of those buried desires are aimed at the entertainment industry as opposed to the science field. I bet a lot more people strike out for Hollywood on a bus with their last 50 dollars hoping to catch a break than people who head out to MIT to see if they can impress someone and become a famous scientist. Does that mean Hollywood has less substance to it if just about anyone who is ambitious enough could break into it regardless of their experience level or talent? I'd say yes.
Under the current economic conditions people should be grateful to have any job, but I am especially happy for those people who enjoy what they do for a living, regardless of what their work is. I think it's good advice to go into a field that you enjoy. By the way, if any of you happen to know of any openings for positions in the NBA, or for work as a movie critic, comedian, or food critic, that doesn't really require that you are good at it, I'd love to hear about it. I hear it's all about who you know.
