The site describes its name, and its mission, this way: "Discardia is celebrated by getting rid of stuff and ideas you no longer need. It's about letting go, abdicating from obligation and guilt, being true to the self you are now. Discardia is the time to get rid of things that no longer add value to your life, shed bad habits, let go of emotional baggage and generally lighten your load."
To that end, today's tip of the day is particularly inspiring: "Discardian Question of the Day #1: Who would really appreciate this? If the answer is 'Me' then keep it; otherwise send it on to a better home with good wishes."
