Have you read The Artists Way? Yeah, me neither. But I've thought about reading it, and bought it, and read accounts of others who have read it, and read the first 20 pages. But not read it. However, it turns out you don't have to for it to work.
One of its major tenets, and the one I hear mentioned all the time, is the idea of journaling. Or Morning Pages as I believe it's called in the book. You just spill out whatever's in your head onto the page every morning, in long hand, and then your life changes. Except, wait - what? If it was that easy wouldn't everyone do it? But - maybe it's sort of that easy. Not that my life is profoundly changing exactly. I mean I'm no Janice MacLeod, writer of Paris Letters, who quit her boring job and moved to Paris and met the love of her life. That's some heavy duty journaling right there. And also a good book - I did read that one. But I am moving some things in my life positively forward, and feeling relaxed and happy about it, so that counts.
I've dabbled in the morning journal on and off for a few years, and then really committed to it a copule of months ago, and I love it. It's like getting a little insight into your own head. (Although it turns out you need to read back through the stuff you wrote in order to get that insight - at first I was just writing, never reviewing, and that was a little like shouting into the void. Gone on impact.)
So if you want extra credit, actually read the book. I'm guessing there's more going on there that I'm not taking advantage of. Or just write in the journal. The impact is undeniable, even if you don't read the book to figure out why.
