Lim Seoyoung has a master's degree in psychology. She worked briefly at an advertising company after college graduation, and wrote screenplays as well, but what most interested her was exploring her own mind. Life gradually became better as she learned what kind of person she was. She then realized that she had been orbiting around similar concerns all her life, and wondered if people couldn't break free of a familiar path, as planets continue their revolution. Moving away from psychology, she read all the books she came across on the logic of the mind. As she did, she came to realize that "self-love" is the piece that completes the puzzle that is life. Today, she is a psychological essayist who writes on a variety of topics.
