The 21st century human being is an ever engaged being;
A busy bee or better still a buzzing being.
To him the 24 hour day is grossly inadequate and thus he always has tons of undone tasks.
This causes him to undermine his efforts. “I’m not doing enough!” he asserts.
The truth is, we all want to do more, be more and have more. In short, we crave increased productivity.
To be more productive you need to literally do more. Great, this is why you pick at several tasks.
