Write by hand. Drs. Carrie and Alton Barron, authors of The Creativity Cure, advise us to skip the Microsoft Word doc and pick up a pen instead. Sometimes the whole experience of writing by hand — the ink on our fingers, the smell of a fresh notebook — is all it takes to get our creative juices flowing.
I adore my Mac and iPad, but NOTHING beats writing by hand. With J Herbin inks, and Clairfontaine paper, writing by hand is paradise.
Tip: refilling fountain pens is messy. Use plastic gloves. Beats scrubbing your hands frantically if you've got a meeting to attend. :-)
