Study what you want to study. It is YOUR life. Have a talk to your parents about how you feel and let them know that you want to do what you want and then go get some dancing lessons. Do your own goals not someone else's.

When you do what others tell you to do, you will not be happy.

It's never too late to change the paths you take in life. Goodness... After I do my own goals of baking and owning a bakery for so many years I may start my own art business or even go back to college in my 50's and do something else. I think that would be fun.
