Joyce Wycoff, co-counder of Innovation Network, has a great list by Hugh MacLeod posted on her Good Morning Thinkers blog about how to be creative in a non-creative world.
I love number 6:
Everyone is born creative; everyone is given a box of crayons in kindergarten. Then when you hit puberty they take the crayons away and replace them with books on algebra etc. Being suddenly hit years later with the creative bug is just a wee voice telling you, "I’d like my crayons back, please."
