Well, of course, YANBU.. art is really important.
But if I'd paid more attention to economics and business studies, I might be a bit better at selling my art.
Approx half my income currently comes from freelance illustration, but art classes in school is not where those skills came from, I am almost entirely self taught (alongside some strong influence of a friend of my parents)...
What stopped me doing this sooner in life (I stopped doing anything arty until about 4 years ago) ... was lack of confidence/self esteem/sense of self worth.
So yeah art is really important, art should be taught the VALUE of an artists work, in terms of time, materials, effort, skill... should be taught..
But giving kids the confidence to express themselves is really, more important and unfortunately I find the traditional school system works very hard to squash kids individuality, independence, expression etc.
floats off moaning about how school crushed her artistic soul
