I believe that things always come around full circle.
Centuries ago, humans were very creative. It was a way of living. Creative expression was key in handling day to day affairs. The right brain was being used to its full potential.
Then, suddenly, the left brain became the dominant one. It was more important to be logical and rational than it was artsy and playful.
But that's all changing. I recently read an article on how creativity is a requirement when applying for jobs. Employers are seeing the benefit in using the right side of the brain more frequently and encourage employees to use their creative minds to get the job done.
There are also a few books out there worth perusing:
The Rise of the Creative Class by Dr. Richard Florida
The Flight of the Creative Class by Dr. Richard Florida
A Whole New Mind by Daniel Pink
