You will probably see a fair number of pics of Calvin on this blog because:
A) he's as cute as the dickens, and
2) I actually learn stuff from him
When I take him for walks, he will often walk and look backward at the same time ... kinda like this pic (although my calling his name from behind with a camera in hand didn't really help him in his looking forward). I'm sure the fact that Calvin's a 15 lb ball of fluff who's been attacked on 3 occasions by a 60 lb evil German Shepherd plays a role in his walking habits. But, it can be rather frustrating for me the walker. It makes forward motion kinda tough some times.
I can pull a Calvin on occasion. Keep looking back ... sometimes it's at the rough stuff of life -- the regrets ... the coulda, shoulda's of life, but sometimes it can be at the good stuff too. And while reflection is a good thing from time to time ... it can also really hinder forward movement.
I suppose the lesson to be learned is the balance of when to reflect and when to push forward.
