I believe in the importance of formal art education. However not everyone has the time nor the means to do so.
There are many in the arts community who will tell you that the key to creativity is to lead a chaotic life. This may derive from the fact that many of our art heroes led difficult and outrageous lives.
Creativity doesn't survive in chaos. As artists we need to create large tracks of time in which peace exists.
It was important for a collector historically to know where an artist studied and with whom. If an artist didn't have the right pedigree then there was no client.
Igniting the creative flame within requires us to let go of the known and venture into the unknown. Learning to let go is one of the greatest secrets of living a fully creative life.
