I love this post by Darren Kuropatwa who talks about the transformation many, including himself, experience from just taking a photograph a day of their own person and surroundings. I find this fascinating and the links are great. This is a very rich post and insight into the types of things that cause change.
To me, reflecting on my blog is sort of an internal snapshot of my thinking at the moment and has been fundamental to my own transformation. Sometimes when we observe ourselves from a distance, we are able to make changes right up under our nose.
