Happiness = 1/abs(SLO-SLI)

Happiness is inversely proportional to the difference between the satisfaction level of what you do to live and what you love to do.
Formula: h =1/abs(SLO-SLI)

If SLO= SLI OR SLI = SLO.Then, h = ∞. (Infinite).

Hence proved.You are infinitely happy ifWhat you do to live is what you love to doOrWhat you love to do is what you do to live.
