"Meditation suffers from a towering PR problem, largely because its most prominent proponents talk as if they have a perpetual pan flute accompaniment. If you can get past the cultural baggage, though, what you'll find is that meditation is simply exercise for your brain. It's a proven technique for preventing the voice in your head from leading you around by the nose. To be clear, it's not a miracle cure. It won't make you taller or better-looking, nor will it magically solve all of your problems. You should disregard the fancy books and the famous gurus promising immediate enlightenment. In my experience, meditation makes you 10% happier. That's an absurdly unscientific estimate, of course. But still, not a bad return on investment."
