I think that if you want to pass emotion, you have to write a letter. Emotions do not pass in SMS or in e-mail.
I don't think that you can write music if you don't know how to play an instrument. You have to know the basics, then you can go forward.
A singer can quit once he or she has made ten great songs; a director can finish once he or she has made five amazing films; a writer just needs to write three great books.
