Everyone has a masterpiece in them.
Why gate access to your work, your creation? Of course everyone has to eat and pay bills, but there are other ways of achieving this rather than hold back the distribution of your vision.
Sponsorship. People want to be heard, and will pay you for the chance to attach themselves to a vision they believe will gain following. If your work isn’t good enough to inspire this, then maybe you need to reevaluate your wares. Perhaps a different medium would better suite you. Just always believe in that one masterpiece. It is available to you. Just keep an open mind as to what it might be, for once you find it, there will be no more uncertainty.
