Most, if not all us would want to grab of what we thought an opportunity made available for us. Some would also try in any means to create an opportunity for them and make sure nobody could block them in grabbing it. I would say that the former is a normal case. We waited for chances knocking at our door. The latter is self-serving and more of a desire of getting something without consideration of whether he is fit or unfit for the position. Worse is, many will be affected. Many wouldn’t want you close in their yard, thus making you an unwelcome visitor and everybody wants you outside the door.
People must understand the nature of life. Each of us has our own share of work to do in this society we’re living in. Work and do your best on the tasks already placed in your hands. If you’re good at it, others will recommend you to get more works to do. But if you haven’t proven yet your worth by doing the things assigned to you, I don’t think you deserve to ask for more. Anyways, we have our own reasons for the all the actions we make. Whatever reasons there are, we make sure, it is for the benefit of the MANY, NOT FOR ONESELF!
