I periodically tidy my thoughts, especially where creativity is concerned.
I find the road to an uncluttered mind, when you deal with so many issues of others, is to return to the basic influences which brought you to the path in the first place.
In drawing, Klee’s Pedagogical Sketchbook, painting, The Sketchbooks of Picasso, copious online images by Jean Michel Basquiat, Mark Rothko, Robert Motherwell, Willem de Kooning and Francis Bacon, the sexy fashion complexity of Versace, amusing myself with quotes from Joe Orton and Edward Albee, the glorious poetry and music of Van Morrison and Eminem, the sharp end of Leo Burnett and 72nd and Sunny and finally purging my mental ball of string with a reminder of the Seven Principles of Zen.
There may never be a more simple goal to describe and a more difficult one to achieve, but if you let these principles wash over you and creep into your daily life and work, you are bound to feel more centered and able to deal with all that life brings.
