Give It Away
When you have too much, give some of it away. A common rule of thumb is, if you haven't used something in a year get rid of it Set aside an ongoing bag or box for charity. Each time it gets full, make a run to the local drop-off bin, or call a charitable organization that picks up items at your doorstep.
On garbage pickup mornings, all the trash should be in the container on the curb none in your house.
