Its not the kind of work you do but your way of working makes a lot difference to what you have in store at your work place. Your contribution to the organization also depends a lot on this fact. Never mind what you want to do or what you are asked to do, because you just cannot understand, at times, the broader spectrum and hence cannot decide what you have to do. However, keeping up the openness and clarity of thought in your way of working makes sure you get what you deserve although not what you want!
After all, as a matter of fact, getting what you deserve is more important and fair enough than getting what you want.
