Indeed, and very true.
Right after posting this, I also thought about artists and art (since I'm in the gallery business) and how some artists feel very uneasy about "pricing" their work... and the high correlation between that philosophy and the stereotypical "broke and starving artist." By contrast, the artists we represent who see "value" in their work also tend to be quite commercially successful... not because they have "big heads," but simply because the feel that what they offer is of value.
Thanks for your thoughtful comment!
