There is no equality in this world neither is there fairness. If everything is just so perfect, this world will turn into one eerry place. You won't learn to cherish, care and feel for others. Sometimes, its everything little things you do change the people, the events around you. Even though the majority do not know how to cherish what you have done, there will always be a minority that see you as their angel. We can't change the world but we try to shape it, mould it into a better place for mankinds. These are all human natures -presence of angels & demons. We are not god, we are just simple mankinds. We do not have the power to change the entire world, we must understand our limited capabilities. You have put in effort, you have played your part. Have faith in yourself.
