Live Like a Lab with a Ball

What would you experience and accomplish if you cast off dwelling on all the hardships of life and work and sour people and the world and past griefs and traumas and instead just enjoyed moments as wholly and purely as a Lab doing nothing more than delighting in the unencumbered joy of anticipating and running after a ball?

What might I achieve and feel and who could I “raise the tide” of if this was my new mission for my life and the lives of everyone I interact with?
