Over the weekend I finished reading A Dog's Purpose by W. Bruce Cameron. If you haven't read the book I highly recommend doing so. It is brilliantly written and gives a dog, who has the ability to recall past lives, a voice. He is able to see how things he learned in his previous lives progressively helped him in whatever current life he was living. The book helped me finally get a message I have been refusing to learn for several of my own lives, including 75 years of this one.
The message/lesson: When I see a pile of dog poo in my path it is only my responsibility to shout out a warning to anyone following me; it is not my job to actually pick them up and carry them to a cleaner place.
