Where do you get your characters from?

I sometimes do a page on them in the beginning in three parts, physical – what they look like, social: where they live, who their family is, education, work etc then lastly, psychological: what they want, their goals, dreams, ambitions, disappointments, hang ups – everything that makes them the individual they are. After that, I often go through magazines and see if I can see a picture of someone who looks like I imagine my character then I’ll cut it out and put it on the notice board.
