Recommended by a coworker, the Panda Planner ($31) is supposed to help cultivate productivity and happiness, with a morning review section in which you can jot down affirmations and what you're grateful for on a daily basis. It also prompts you to choose a monthly habit, check off a box each day you complete that habit, and reflect on your progress at the end of each month. Plus, it comes in five stylish covers with a cute panda on the front of each hardcover book.
