What I came up with (while running of course) is that first it is totally overused. I bet you could interrupt a gaggle of high school girls and at least one of them would claim to have met the love of her life. Second, I don't think you can really know the love of your life until your life is coming to an end. Ask almost anyone that has been divorced or has ended a long relationship, and I'll bet they called their former significant other the love of their life at one time or another. Third, I think you can have more than one love of your life, which kind of takes away from the whole concept.
I am a perfect example of multiple loves. I would say my husband and my girls are the loves of my life. I obviously love them in different ways, but I also can't imagine my life being complete without any one of them.
If I want to take the idea to a whole other level to further prove how much of a truism it is, I could call running a love of my life because I love it and I plan to do it the rest of my life. Or reading because I have always loved doing it, it makes me happy, and I plan to do it for the rest of my life too.
Well, we might as well take this all the way. Who and/or what are the loves of your life?
RUN: My running miles have been low this week, however I am getting to know my bike pretty well. My legs haven't been happy to hit the treadmill, so I have been taking advantage of the opportunity to cross train by riding the bike (and loving the chance it gives me to spend some time with one of my loves...reading).
