Things you wish you didn't throw away. →
[More:]I've always had a problem with keeping myself organized. My sister is a master of organization and has helped me numerous times to organize the rooms in my house. Several years ago she was helping me clean out my home office and came across a book on how to paint canvas floor cloths. She held it up and said, "You will never paint floor cloths." and threw it away. She was probably right but I still think about that book.
