Life and Destiny

None of us came here of our own will, but were put here by our parents. Since we were all born the same way, and are thus all equal, we should all do our best in life, but only a few of us actually achieve success. Some of us are satisfied with our current status and think we should be grateful for what we have. Others of us, who are never happy with our condition, see this world as a boundless sea of endless troubles. Is there some preordained destiny that controls our lives, or is it all just chance? Only one thing is certain: it is useless to complain about fate. We can try to make our own fortune, or we can passively allow to happen whatever develops.
