What you are called to is your 'art.'

Do you see yourself as an artist?

In a broader sense, an artist is someone who refuses the tired and mundane scripts being offered, in exchange for the chance to actually change people's lives. Really change people's lives.

The artist intends to reveal something through his art.  There is a declaration behind it.  [Otherwise, the art becomes merely self-indulgent].  The art is the access point to a deeper, somewhat veiled, reality.  It provokes us, stirs us, and tells us rumors of another world. The resulting creative work is the artist's calling card, a trail of breadcrumbs that lead 'further up and further in' to this other world.

Not all artists paint or work with clay. It's not so much the tools of the artist that matter. For one artist, the medium they work in, is relationships. For others, it's the ability to bring clarity into confusion. For another, it's the art of piercing the darkness with beauty.

It's how the artist SEES that matters.

Linchpin - Are You Indispensable, by Seth Godin.  Not a 'spiritual' book, but surprisingly reflects biblical values of giving without expectation, creative freedom, and the idea that all are endowed with genius that can change lives.
