I'm open for different opinions, but in my view, being more productive for its own sake is fundamentally misinformed. Being productive means being more efficient at producing output. To get there, you need to put effort into optimizing your process. This effort is only worth it if you know that you NEED more output, in order to reach some OTHER goal. More efficiency in of itself is a misaligned goal. It doesn't lead to happyness. In fact, it seems to me, most of those gurus, and their followers seem to be about boasting their productivity dick. It's like flaunting money: a status symbol that doesn't make you happy in of itself. If you're making honey because you think just simply having money will make you happy, you'll be leading a miserable life.
