Maybe my memory is bad, or perhaps I'm subconsciously "lying to myself," but I don't think I lie anywhere near as often as the author believes she and other people do, even about tiny things.
Actually, while it might sound cool - I don't really recommend this course of study. It would almost certainly NOT make you a happier person. "For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow." (- Eccl. 1:18)
In natural speech, people generally make simplifications that edge towards oversimplification, or omissions that could be considered misleading if the omission is not fully understood by both parties, or false statements just because of a personal misconception (perhaps only realised later). That's a natural part of communicating at a reasonable speed.
Eliminating those occasions takes real effort towards communicating well.
Perhaps you don't consider those "lying" as such, because they're not deliberate attempts to mislead. But the boundary between these and deliberate "lying" is blurred. Your motivation for communicating with these shortcuts is a deliberate choice that is worth reconsidering occasionally.
If you can avoid those white-type lies 100% of the time, I applaud you. I don't think it's easy and few people manage it.
Of course, when you get into simplification and omission, things get more complicated. I've absolutely simplified basic things like where I'm from, or the exact timeline of my education, etc. And every time I say anything, I'm omitting, well, everyone that I don't say. The line there is definitely blurry.
