Have you ever just had a bad day? Or a bad experience that you just couldn't let go of?
I know, it's hard to see when you're in it, but it's possible that a new day brings new opportunities. Today is a new day. Yesterday might have sucked (hey, it was a Monday) but today can reveal new gifts and new perspectives. Don't focus so much on what happened yesterday, because you just might miss the wonders of today.
