About a year ago, I started my first “art journal”. (more scans from my journal on my Flickr)
It surprised me how quickly I came to like this art form. My journal doesn't contain “journaling” in its true sense because I keep a daily journal and – being slightly socially awkward - I don't want to share my deepest thoughts with anyone. But... it allows to show my mood and a little bit of the “real” me without revealing too much.
