The things that keeps me from throwing stuff out are:
1. I'll donate it (never do)
2. Maybe a friend can use it
3. I can sell it on-line (never do)
4. It has some sentimental value
5. I am lazy and don't want to take the time to go through the stuff
6. I don't want to waste stuff
7. I don't want to fill up the landfills
8. I might need it one day!
9. I just don't know what to do with it
