When customers noticed and began telling her the drawings brightened their days, Mari realized she could use that hobby to connect with people. She hit a professional rough patch in her late 20s and began to chronicle her work on Instagram. Nearly overnight, she became a sensation. Now when Mari Andrew posts something new, the Internet rejoices. This book is organized by universal themes of becoming an adult--for example, loss, adventure, ambition. Within each chapter, Mari shares her personal experiences in never-before-seen essays, accompanied by spreads of her signature illustrations, 90 percent of which are brand new. Readers are bound to see some of themselves in this book, whether seeking advice on how to handle growing up, or just looking for a friend who can commiserate.
