Who is the Player?...Who is the Umpire?

Have you ever got a question of this sort?
Why it pinged me.....want to know?Then go through this.........

Why do you buy a particular pen?Because you think it writes well!
Why do you put on switch when you want air or light?
Because you know only then it works!!
Why don't you take more and more sweets/food at a time?
Because you know that you will become fatter (it would cause a problem later)!!
In all the above cases (of-course very simple stances) you anticipated the result knowingly or unknowingly...right!?

Then, why people say that what Lord Krishna in his revelation told "keep your effort,don't think about the result" as the sole SUCCESS mantra?
Will it be really possible.....!? For one or the other reason, we anticipate the result before enacting.In other words, we can't make effort without thinking about the result....for that matter, the concept of "DREAMS" is the euphemism for this...is it not?? Now, with enough reasoning I think I have got a right to think about the result.
At this point of time,with many experiences, I would like to question....."why the result is not always proportional to effort?"...(atleast in my perspective....as according to my observations and/or experiences.)
Basically, I'm ineterested to know if there are any metrics for this.Can't we measure effort?How come,an immeasurable quantity(effort) is giving a 100% measurable quantity(result)...
Ok! If there is no metric, is there any boundary atleast?
To find an answer for this is difficult though not impossible ...!!
Because,we know that effort is nothing but trying to learn/acquire/do something.
Learning is the movement from moment to moment.And, it goes on and on till the last breath.But, till then if the umpire(say The Almighty) waits to evaluate the effort(in his own metrics) who will enjoy its results(/consequences).
Seems to be wierd!!?? But, think on this....it will not be so..(atleast to me)
Why because, I am a person who doesn't care on the short term inputs/outputs.
I count my efforts on a long-term basis.
According to me,if you are a farmer, you should eat the fruit, or tell whether the field yields good crop or not,or perhaps you are the person who monitor the lands yield......Then why not the same case over here.Why should our effort be evaluated by some others when we are intelligent enough to count our bucks.
So, if I make an effort, I am the person who can award/reward it or can collapse it.....But, not my fate!
And hence what is that I want to put before you is.....
" If you are an intelligent Player,then it is you and no other will be the Umpire " !!
