It might help to think of music as a fundamental part of who you are as a person rather than as a career. Your vocation does not define you. It pays you. There's a difference. Your artistry lies much deeper under the surface. It changes how you think, how you see the world, and how you express yourself. Your music career is not limited to a few moments in the spotlight. It is lived out over the course of your entire life. Musicians create music because they are musicians, not only for the money. If no one was listening, we'd still play. We are compelled to do so.
In my extremely humble opinion, you may want to spend some time thinking about what it is that really want. It's one thing to say that you want to make a living as a musician. It's another to define for yourself exactly what that means and then chart a course in that direction. How flexible is this plan? If life throws the unexpected at you (and it will), how will you adapt? Some people say that you should hurl yourself into the unknown with no reservations and no backup plan. Others tell you to protect yourself with alternatives and backup strategies. The bottom line is that no one else can tell you what your decision should be. We can only tell you what we chose when we encountered these questions. There is no single path to take as a musician. There is, on the other hand, the artistry, which will pulse through your soul for the rest of your life.
