Most artists just feel the need to explain their work.
Regardless of one’s ability to write, writing about your work
poses unique problems that very few artists are equipped
to deal with. Consequently, most artists’ statements
become overly personal explanations about what art means
and what they are trying to accomplish in their work.
Every artist wants his or her work to be
understood and appreciated in the context in which it was made.
However, very few artists are  able to articulate intelligent
insight into how to achieve that level of understanding,
nor should they.

Part of the joy, from an observer’s point of view comes from the
primary experience with the art bringing to his or her own
personal and intimate connection.
If those things are spelt out for them, before they have
an opportunity to develop that connection, a huge part of the
experience of appreciating the art is missing.
