From time to time I go through a phase where painting only when I'm at home is not enough and I find myself drawing or doodling on whatever piece of blank paper is on my desk.
For my lunchtime yesterday I went to the Mugg & Bean coffee shop not too far from my office, with my small sketchbook in hand. It is amazing how fast that hour passes when you are drawing. It was quite challenging to draw someone who is not posing, they move around and shift position all the time. I really need to do this more often.
So as the coffee cup coaster says:- Do what you LOVE, LOVE what you do.
