The Introvert Activity Book: Draw It, Make It, Write It (Because You'd Never Say It Out Loud). Conventional wisdom suggests that people who don’t speak up have nothing to say, but introverts simply prefer to express themselves differently. Introverts are known for their creativity, their need for thoughtful reflection, and their preference for solitary activities, such as drawing and writing. The introvert activity book offers doodle ideas, lists, paper-craft projects, writing prompts, and so much more the reader becomes the author.
