Harvesting Quotes

This morning, I "harvested" quotes that I'd hastily copied in my datebook over the past couple of months while reading at Borders (usually).  I find it interesting what subjects capture my interest...Some are not direct quotes but notes to myself adapted from something I read.

• Negativity is like rocks in a backpack
• Look at all the beauty that surrounds you and be content that it's enough.
• "Crossing too many t's and dotting too many i's make a room look overdone and tiresome.  One should create something that fires the imagination without overemphasis."  (Nancy Lancaster)
• Joy is a net of love by which you can catch souls.  (Mother Teresa)
• It doesn't matter what you wear; rather how you wear it.

Do YOU write down this kind of stuff?  Where do you record it?  How do you store it? Why do we DO this???
