Should I supposed to be more aggressive?

Why is it everytime, anything that I wish for it, be the first who asked for it first, and in the end I will be the last one to get it? It is damn F unfair!!! I am fed up of these. Is it need to be more aggressive to get something when you really desired? Is it need not to care others feeling when you really want it? Why am I always be the one who care others feeling but not others to care mine? Was this I really want? Or is? I am just like being a fool to care, an idiot to feel others feeling. TMD!!!
