In French, “cultiver son jardin intérieur” means to tend to your internal garden—to take care of your mind. The garden metaphor is particularly apt: taking care of your mind involves cultivating your curiosity (the seeds), growing your knowledge (the trees), and producing new thoughts (the fruits).

the goal is to make sure all the information you consume (your input) can lead to increased productivity and creativity (your output) instead of festering and getting forgotten in your mind backyard.
