One who does not ask a question remains a fool forever. The important thing is not to stop questioning.
Curiosity has it 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 to comprehend a little of this mystery every day. Never lose a holy curiosity. One day at a time. Experience is a dear teacher, but fools will learn at no other.
