Drawing and creativity are critical parts of human communication and personal expression, and are essential for success in every profession. Drawing is especially valuable because it improves hand-eye coordination, as well as your understanding of form and shape. It also lets you quickly communicate ideas that may be difficult to put into words. To help you hone your skills, Von Glitschka has developed the 21-Day Drawing Challenge. The goal isn't to turn you into a professional illustrator or fine artist—it's about improving your drawing skills and creative thinking, no matter if you're an expert or have never drawn more than a doodle on a notepad.
