If we compare our lives to the Cosmos, how can we make our carrier, as our life span is too short to be specialist on something, we can carry the job that's not been completed or take forward to the more developed way by our past thinkers, as we are ordinary people, we can't think deep into the cosmos, it will make us hopeless, but it’s sure that our pride, gravity, careless all these will go away from our heart. thanks.
