We keep too much and then get overwhelmed by what we have. Pick something to throw out today. Recycle it if you can but remove it from your home and your life.
Something already garbage does not count. Be fair and give yourself a break.
Give up on fixing something broken. Find a way to give it to someone else (like leaving it at the bottom of the road for someone else to pick up).
Give away something you have not used in years. Consider trinkets and gadgets gathering dust. Offer them to family and friends so someone else can get more use out of them.
Use old stationary to write a letter to someone. The catch is you have to mail it today rather than leave it for tomorrow.
