Teaching as a vocation

I agree whole heartedly that a vocation describes work that results in service to others and personal satisfaction in the rendering of that service, as the author puts it. The article talks about jobs, which are significantly different from a vocation. I have had jobs before, many, many jobs. Jobs which simply, provided me my means for survival. Nothing more and nothing particularly less. Thinking of teaching as a vocation, as something that I am called to do, excites me. That is to say, I feel that I have been called to teach music. I intend to devote myself to teaching and have me being a teacher become part of who I am. Though this begs me to wonder, do I feel it is part of who I am already? I would think logically it must be, if that is what I aspire to be. Thus I am already a teacher and am acquire the skills to better teach my students.
