The world is full of people who are willing to do everything in their power in order to achieve success. Sometimes, successful people are considered as great ones, but real greatness, according to Twain, lies in how much you are willing to share your knowledge and passion for growth with others. Successful ‘great’ people are often arrogant to the weaker and little men. Real great ones are those who inspire the willingness to be as great as they are. They do not belittle you. They bring you up and show you the sky is the limit.
