I typically do a number of sketches and doodles throughout the day while I'm working, talking on the phone, etc. Jon made a good suggestion that I start a "doodle file" where I drop all of my sketches instead of just pitching them at the end of the day. I then thought I could post some of them. I can't promise that I will have one every day, but I will try to keep it fresh and interesting. Enjoy!
