Personally I am all for goal setting and delivering. I’m also very aware that I as a person many times am perceived as very selfish for the fact that I set my goals after what I want. On the other hand in my quest to fulfill them I do not play foul or I hurt people (at least not consciously) I simply play by the rules.
Many people also claim that it is hard, to get what you want. First of all finding out what it is you want and then make it happen. But is it really? Of course it will demand lots of you for a longer or shorter time. But when you know what you want and why, it will be so much easier to stand up for it.
So go out! Find out what you want and just get it.
