I believe that splitting your concentration and even – gasp – multitasking means you end up with lots of things not finished. Probably not as good as they could be, either, but chiefly unfinished. Writer James Clear argues that there’s more to this one-thing-only approach, though, and he starts with trying to prove its value:
If you want to master multiple habits and stick to them for good, then you need to figure out how to be consistent. How can you do that?
Well, here is one of the most robust findings from psychology research on how to actually follow through on your goals:
Research has shown that you are 2x to 3x more likely to stick with your habits if you make a specific plan for when, where, and how you will perform the behavior. For example, in one study scientists asked people to fill out this sentence: “During the next week, I will partake in at least 20 minutes of vigorous exercise on [DAY] at [TIME OF DAY] at/in [PLACE].”
Researchers found that people who filled out this sentence were 2x to 3x more likely to actually exercise compared to a control group who did not make plans for their future behavior. Psychologists call these specific plans “implementation intentions” because they state when, where, and how you intend to implement a particular behavior.
