Substract your past,
Pain will be divided by parts.
Add more to your present,
Disgrace will be multiplied by zero.
Integrate your future,
Probability of happiness will be the highest.
Life is about permutation not combination,
As order is important.
In the sequence of life doings,
Focus on the series of mistakes and learn.
The idea of incessant agony is a myth,
So derive smile.
