This chapter focuses on professional implications of journal article publication. It has five major sections, Intuitive Thoughts, Mark and Hulio, Professional obligations, Professional challenges, and Practical suggestions. It starts with a discussion of intuitive thoughts of graduate students and then a discussion of two real-life cases (Mark and Hulio) so that we can see how new authors think and act related to the central question of the chapter. After that, two core concepts, Professional obligations and Professional challenges, are discussed in detail, followed by several practical suggestions. In brief, there are two major implications. Publishing journal articles not only concerns major professional obligations to disseminate knowledge and improve human life but also generates various professional challenges of communicating knowledge scientifically.
