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.
To be a star, you must shine your own light, follow your path, and don't worry about the darkness, for that is when the stars shine brightest.
Always do what you are afraid to do.
