" How do you decide which [books] to keep and which to give away?
...Four categories for your books, regardless of which room you keep them in:
- Books you own but have never read and don't realistically expect to read. Don't hold on to them for "someday". Donate them today.
- Books you have read but will never go back to. Donate these too.
- Books that you have read and that have become influential in your life. Keep them...
- Books you have already read and know you will want to return to. Of course, keep these.
Shelves looking better now? "
