THE EQUATION OF LIFE !!

Its not that I am a philosopher or anything like that.. but in the last 3 months when i tried to go in the flashback and reviewed my life i found that it has always been centered around different people (read variables!!).. i have always lived by the philosophy that my happiness lies in seeing the people, who matter to me, happy!! now i have always said to others that centering your life on a single individual always makes you susceptible to misery and pain because your happiness becomes centered around that very person.. if we take our life as an equation its very similar to the equation being dependent on one single variable.. but i think the problem with people like me is that for us there are a lot of variables and each variable affects our equation.. some affect it less.. some affect it more.. and to some we give the power to even completely erase this very equation !! another aspect of this equation is that the variables that are affecting this equation are completely unaware of its fate.. they are a different entity and their personal equations are going independent of the central equation i was talking about.. its very easy for them to detach themselves from the central equation.. but the central equation is the one getting adversely affected.. so the moral of the story is that more the number of variables in your life the more problems.. and try not to go in the path of the central equation !!
