When you have to choose a career, a lot of people say "Do what you love". I think this is extremely naive; it is definitely not that easy. I love to sleep, but I can't make a living off of that.
The ideal career path for a person has to fit three categories:
- It is something you are good at.
- It is something you love doing.
- It is something people will pay you to do.
If the answer to all of those is "yes", then that is the perfect career choice for you. When it comes to the piano, you've got to ask yourself those questions when making the decision. Not only do you have to be good at it to be a pianist, you have to be very good, or people won't pay you, and you definitely have to love doing it; especially if you are going to be a teacher.
Choosing a career in music isn't just about "doing something you love". There is more to it than that; there is a lot of competition.
