It seems easy to do when you’re told to just focus on a single task to get things done. On the face of it, it shouldn’t be hard to learn how to focus better. But people aren’t naturally prone to concentrate on a single object or task for an extended period of time. In fact, one study sponsored by Microsoft discovered that the average human attention span lasts just 8 seconds. That’s a ridiculously short amount of time, as it’s shorter than the attention span of a goldfish.
