If I were to say something about life in mathematical sense and set theory in particular I would say that life is an universal set and everything else is a subset of it. Similar to set theory, even in life there is a combination of union, intersection, subset and the rest.
Most of us work in one job or the other. Thanks to the IT-BPO revolution we now work at all shifts on all days, simply put 24x7, 365 days a year. Though we have different shifts and timings of work, commonly people refer working as a "9 to 5" job, guess due to majority of the population working in this shift. 9 to 5, 8 hours i.e. 1/3 of our day, that transforms to 1/3rd of life, working.
Agreed our job earns us bread and butter, but life is not all about slogging for few hours more than required and impressing someone sitting ten thousand miles away for a few dollars. What's the point in impressing someone whom we haven’t seen, haven’t known personally and probably has no relevance in our life versus neglecting the near and dear ones who matter the most? As a result of our efforts in life we might get promoted, get increments but are these more important than yourself? For instance one might become a Vice president or even the CEO at an age of 35, but can he become a successful son, parent, husband/wife? The possibilities look remote.
I recollect one famous saying of Prof. S. Radhakrishna who once quoted "Do not lose your foothold on earth while trying to sweep the skies". In chasing professional success we often tend to forget the basic things in life.
When we split our day into three parts, one third would comprise of sleep, one third of our work and the remaining is what is left for US (our use).
And even in this one-third (which comprises of OUR one-third) we will have to account for a lot of other smaller things like taking bath, travelling to office and other miscellaneous things. And when if we were to look back, we will find that we have done very little or probably nothing for yourself and your family. It is time we change this equation and make a winner of yourself in the maths of life.
Work is a subset of life and life is not a subset of work
