I am a piler, and also like to use my inbox as my to do list, but also keep an email draft up to date that is truly my to do list. The top of the desk is usually where I keep things for two - three days while considering or looking through the project, opportunity, task, book, or item. Is that necessarily a bad thing?
How about you? Do you clean the ole desk off at the end of every day, or keep stacks and the organic feel for multiple days?
