Another great Facebook find regarding not worrying about things from the past/things that you cannot change,
I was raised by a single mom with 4 daughters! There were a few times my mom had no car, but thankfully everything we needed was in walking distance. I remember walking almost everywhere when I was young and I remember one time in particular I wasn't paying too much attention and I must have tripped a bit. My mother, after making sure I was okay of course, made up a little song about how important it was to "look where you're going, not where you've been".
I have remembered that phrase, perhaps because she sang it, throughout my life. I've never thought about it's "double meaning" until today.
