I think they key to answering this question is to consider that Guillermo asked about a career in music, not in a career as a musician--you can study to become a recording engineer, become a disk jockey, or, if you want to make the big bucks in music, you go for a law degree with emphasis in music contracts and copyrights and combine it with an MBA--The horrible truth is that even the most talented and most popular musicians have a long hungry climb, a short time at the top, and a a lot of time after to think about what happened to all the money--
