Success can have different meanings for different people. According to Albert Einstein, success is achieved through work, play, and keeping your mouth shut. The keys to success include having a single clear goal or idea, believing in yourself, working hard, being inspired by others, being creative, flexible, and having a positive attitude. It is important to be a person of action, remain determined even in the face of challenges, be disciplined, and never give up. True success is achieving goals that are aligned with one's principles and religion, so that one is satisfied in both this life and the afterlife.
