Geez, I wish I would have written the below post on being creative, but alas it was written by a briliant fellow, Hugh MacLeod, who also does those funky business cards you've seen somewhere and tons of other creative renderings.
And while this post is some 3 years old - it's still one of the best damn posts out there on "How to Be Creative." I particularly like #2, #4, #5, #6. Which one is your favorite and why?
Now go and pick up those damn crayons, or your favorite pen and start creating just for the heck of it! My kids do it all the time and the stuff they come up with is pretty amazing.
