When I think of the meaning of my work, I think I'd rather talk about what fascinates me instead. I find that the more I try to find meaning as an artist the more elusive the attainment of that understanding becomes. I also find that when I decide that a body of work will be "about this" it ends up feeling really contrived and mannered - two things I detest.
With that said I do realize the importance of speaking about your work and taking a moment to know what you're about as an artist. I'm in the process of reevaluating how I define myself.
