I have not decided what I would do when I'm an adult. Choosing vocation - not a simple matter, because interesting professions in the world very much. Maybe I'm a doctor and I can defeat the most insidious disease. Or, piercing the outer space, to visit other worlds. And maybe I will study the mysterious corners of our planet, or loans to the cultivation of grain. Or, I go to the scientists and find a new source of energy, or simply invent a kitchen robot, which will be in place mom cook dinner and wash the dishes. I'm just a fifth-grader, and I find it hard to say what I will. But I perfectly understand that the knowledge acquired at school, will certainly help me in the future, when I get to work for the benefit of society.
