Good health is a pathway to great happiness.

It is hard for some to be happy when healthy and it is even harder for anyone to be happy when unhealthy.

Happiness can be found in overcoming not unknowable obstacles in the achievement of a knowable goal.  In other words, good health will not reveal happiness.  Overcoming current health in the achievement of better health can reveal great happiness, which can be supremely enjoyed when the goal of great health is achieved.  It is the successful journey, and not the destination, that makes us happy.

Take a walk, ride a bike, eat a salad. Have fun in all that you do to become healthier, ergo happier.
