A few weeks into my sketchbook and so far I realized two very important things. First, there's nothing better than starting your day with your sketchbook. I notice such a difference in the days that I do versus the days that I don't.
And second, when you give yourself freedom to do whatever it is you want (for once) and try to not limit yourself, your sketchbook somehow streamlines itself (where in the past it never did). Funny how things work out. Freedom is a good, good thing.
