Watch your thoughts, for they become words. Watch your words, for they become actions. Watch your actions, for they become habits. Watch your habits, for they become your character. Watch your character, for it becomes your destiny.
To my mind, this phrase is eternal, because our actions reflect our thoughts and attitude to the world, Then we build our character, which can greatly influence life. And only we are to choose what is better for us and only we make ourselves and we are responsible for our choice.
