Harvard University educated Mel Arat in Extraordinary Life Skills provides skills and tools for an innovative and creative lifestyle According to Arat's theory, there are four types of people in this world: Sub-ordinary, ordinary, extraordinary and supra-ordinary. The extraordinary people are putting assumptions and generalizations aside and making a lot of trials to discover the possibilities and the world. Trials and creative thinking techniques help them to succeed in life. Supra-ordinary people are revolutionists such as Edison, Mark Zuckerberg, or Steve Jobs. They are not only creative but changing the world by diffusing their creative products. Supra-ordinary people come from the pool of extraordinary people. Arat also provides tools to develop skills for being extraordinary: Creative thinking techniques, commitment management method, personal development based on projects, focusing and so on. Harvard Professor Raymond Comeau describes the book as "seriously funny" since the book includes funny stories, examples, and jokes to illustrate the concepts of extraordinary life skills.
