In your planning sessions, you assess your priorities. You categorize your daily activities from most important to least important, and decide where to start. You apply labels, from A1 for the most important task down to C3 for the extras. This system helps keep you on track.
What if you applied the same idea to your workspace? You could categorize the documents and tools you use for your career. Then, you could designate the space closest to you as A1 space for your most frequently used items, then B1 space for specialized tools for periodic projects, and C3 space for your stapler, over on the far end of the desk, encased in Jell-O.
