“When you attempt to multi-task, your focus, attention, and energy is spent switching between your tasks and re-orienting yourself to exactly where you were before you switched. It’s like swimming against the current. Every time you take a stroke, you might only get one quarter of a stroke forward because of the current, and sometimes you might even go backwards despite your best efforts.   It’s an inefficient use of your time that ends up in your becoming well-versed in the beginning stages of many tasks, but never quite seeing them to completion.   The better approach is to be willfully ignorant of everything else you need to do, while giving full attention to one task at a time. In a sense, a lumberjack can only chop the tree in front of him or her, and can’t do anything with a bunch of half-chopped trees. Chopping the tree in front of you will allow you to make better progress on everything more than actively working on it while multi-tasking.”
