One of my best friends said this to me a week or so ago and I've added it to my list of mantras. So many times we "throw something away" (whether it be a person, a habit, a thing) and yet at some point later, we take it out of the trash, dust it off and try it again. If you threw it away, then obviously you had a reason to do so. Picking it out of the trash and trying it again is just stupid. Don't do it!
This week I'm determined to leave the trash in the can.
