Self define me (self-defined)

I'm still a little stuck with what I want to do for my self defined project. I know I want to work with observational drawing of people. I quite like the idea thoughts and conversations. How on a tube journey you can see and overhear so many snippets of other people's lives. The thoughts going on in people's heads. I'm going to stock up on food and spend the day on the tube with my sketchbook. Just to see what I come out with.
