We know delegating to others improves efficiency, but so does delegating to ourselves.
How do we delegate to ourselves? Batch a bunch of like tasks that you would delegate to another if you could, such as processing mail, filing, or other busy work. Schedule a specific time period to get it done and grind it out at that reserved time. Make a game of it! See how fast you can do it. It’s amazing how much can be accomplished when we delegate to ourselves.
