Accountability when you're working alone

Over at Best Practices, there's a great post on the motivation of accountability. Clay Mabbit writes that he's been freelance for about four months, and he's learning the importance of accountability now that he no longer has to report to a boss or colleagues. If you don't want to hire a business coach, he suggests scheduling regular meetings with a friend or family member, just so you have someone checking in with you. If you have other ideas for maintaining accountability as a freelancer, please share them in the comments.
