I doubt there are many things with a better ROI than sitting still and simply observing your mind for a while.

To quote the article:

> [Mindfulness is] about much more than living in the moment. Mindfulness, in the most deeply Buddhist sense of the term, is about an exhaustive, careful, and calm examination of the contents of human experience, an examination that can radically alter your interpretation of that experience.

> It begins with one of the more striking claims made by Buddhism—that enlightenment and liberation from suffering are inextricably intertwined. We suffer—and make others suffer—because we don’t see the world, including ourselves, clearly.

Trying to improve yourself isn't productive? This is one of the silliest comments I've read on HN.

It's HN. People here think sleep is a waste of time and eating is a nuisance to be remedied by chugging nutrient paste.
