Theory of Positivity and Negativity

Sitting idle invites many thoughts, sometimes good sometimes bad. This is how I happened to ponder upon the Theory of Positivity and Negativity. The original theory, as propounded by me, states the following principles:

Everything rather every matter (speaking scientifically) has both positive as well as negative effects. Only thing which matters is the degree of positivity and negativity. Anything could have greater positive effect and lesser negative effect. But that lesser negative effect can suppress the positive effect and can be detrimental. It can be the other way too i.e. anything having lesser positive effect and greater negative effect, that lesser positive effect can very well suppress the greater negative effect.
e.g. A boy who has lost his love. His state of mind will have greater negative and lesser positive effect. But he can, by his strong will, overcome that greater negative effect with the help of that lesser positive effect.

Well, this technical and scientific looking theory can be summarised in one word "Will". It's all about your strong will to brawl the worse situations and in between this brawling, my thoery will come so as to explain this phenomena scientifically.
