If you have a Kindle (or Kindle app), I highly suggest downloading the free book Do the Work by Steven Pressfield. Pressfield is one of the reasons I wake up at 4:40 A.M. and write. His books are inspirational and they actually motivate you to do the work of creating your art — whether that be writing, painting, programming, etc.
The War of Art is another book he’s written that teaches about the “resistance” and how to overcome it. Very intriguing for anyone who has started a project and never finished it.
Do the Work is free right now (4/20/11), but it may jump up to nine dollars soon. Check it out!
And if you find the above books helpful, here are some others you can purchase:
Linchpin by Seth Godin
Poke the Box by Seth Godin
Bird by Bird by Anne Lamott
