I always carry a sketchbook. If you think more than not, I'd suggest attempting to let your thoughts run free across the old-fashioned page.
Having a portable sacred space to figure (draw) out, fashion a-muse and shape ideas with ink - all in complete liberation from slavery to the power cord - is one of life's most creative freedoms. Without a doubt, I will doodle until death do us part.
ALLOW YOUR iDEAS TO TAKE PHYSiCAL SHAPE.
