A dream job is work you love and that brings you a serious income. Many dream of it, but only a few can boast such a job. Who are these lucky ones? Those who constantly try new things, not stopping at what they have achieved and moving from place to place in search of better opportunities, or those who strive to thoroughly master professional skills? What is the key to success — pursuing your dream or professionalism? The author of the book, Cal Newport, a scientist and author of several bestsellers on the nuances of personal motivation, engagingly and humorously, supporting his arguments with results from serious scientific research, convinces us: it is much more promising to temporarily forget about future great achievements, risking ending up with nothing, and to act for sure by mastering the work you are already doing.
