The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity.
Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb.
Please stop waiting for a better and more appropriate time to become happy and focus on the moment you live in. Happiness is not an arrival, it is the journey itself. Many people seek for happiness above the height of human beings, some below. Yet, happiness is exactly at the exact height of human beings.
Life is a journey up a spiral staircase; as we grow older we cover the ground covered we have covered before, only higher up; as we look down the winding stair below us we measure our progress by the number of places where we were but no longer are. The journey is both repetitious and progressive; we go both round and upward.
Our life is a constant journey, from birth to death. The landscape changes, the people change, our needs change, but the train keeps moving. Life is the train, not the station.
