We can learn a lot from dogs.
The world would be a happier place if we did these things:

When loved ones come home, always run to greet them with a happy face. 

Take naps. 

Make sure you are always comfortable. 

Scratch when it itches. 

Run, romp, and play daily.     

Avoid biting when a simple growl will do. 

On hot days, drink lots of water and lie under a shady tree. 

When you're happy wag your entire body and let your face show it.

Enjoy eating and quit when you are full. 

Delight in the simple joy of running through the grass. 

Be yourselfl.  Never pretend to be something you're not. 

When someone is having a bad day, be silent, sit close by, and nuzzle them gently.
