Sorry to post yet another photo of one of the dogs, but …no, actually, no I'm not sorry, they're worth the extra photos.
Bella is 9 and her enthusiasm and joy in chasing the ball is unlimited. And even when I think she's had enough and I go over to take the ball, she's up and ready to go again. Zimi on the other hand, while totally besotted with the balls, and beside himself when it's getting close to "throw the ball time", cannot bring himself to let me take the balls away from him to throw again. I see Bella and Zimi bring such total commitment to what they're doing, their joy and ability to be in the moment is something to learn from, to aspire to.
As Wikipedia puts it: "… joie de vivre may be seen as a joy of everything, a comprehensive joy, a philosophy of life …"
I think that sums it up quite nicely, and I'm pretty sure Bella is smiling in this photo.
