I wonder (only sometimes)

In life, I wonder, I wonder who is a winner and who is a loser... if something like that exists. Is someone who is at the heights of what they are doing the winners and the one who is good at nothing the loser? Or is success and failure measured on the amount of money and fame a person earns, or the respect he gets cos of it or is it based on the amount of people who love him. What makes a human life better than another? How can anyone say or judge one person is better than the other? What would it be based on? I really get confused when these kinds of questions are asked. What are we striving for? Or what should I strive for? Sometimes, I think these questions are unanswerable, unanswerable because, when we don even know the meaning or reason of life, how can we come to know the best way to live it? Are we striving for happiness? Is that the goal ? Or are we a bunch of total meaningless creatures on this corner of the universe that can be washed away anytime just made to think and feel as something important. Are we just like the rocks all around us with just a little more power to make us more and more confused? Is this so called intellect and reasoning just a farce to make us think, make us go round and round just to make us feel we are reaching somewhere but eventually it just makes us rotate insanely and leaves us back at the begining with no answers. We are in such a situation that each and everyone have a definition of life and the reason to live it, but none of them can prove that their reasoning is the right one. It is all based on either assumption, or cos it’s written in some books, or cos our elders were always following it. To come to think of it, we have been put in such a beautiful loop. We have been given a reasoning power, but also with that we have been given a strong set of intuitions or instincts which would try to believe what it wants to. So we assume something’s and then we give some facts on those assumptions and try to establish them as the truth. Every 100 years someone comes along and says the base assumption is wrong so the truth which has been told should be re-written. Initially a group of people would resist, then some would want to kill him for even proposing the same and then gradually we accept and we understand his reasoning power was superior to others cos based on the available facts he had the potential to think so much far ahead. But still, there always are some assumptions somewhere to get the results as we want (this point I started believing since I read about how the light propagates in high school, I am not brainy enough to comment on the theory, but felt we made too many assumptions in there). We were taught "Man is an rational being". But to think of it we are only rational in fraction amounts, else we love to live by how our elder’s leaders tell or the holy book says. If we were truly rational there would be lot less pain around in the world. I think we are a hugely instinctive, emotional people ruined by what we are programmed to do by the holy books, the pandits, the mullahs rather than being rational practical beings. Also I feel how much ever I wonder answering my initial questions in the post satisfactorily is near to impossible, but I still hope, I would find the answers someday ....
