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.
Once you get the hang of it, the practice can create just enough space in your head so that when you get angry or annoyed, you are less likely to take the bait and act on it. There's even science to back this up -- an explosion of new research, complete with colorful MRI scans, demonstrating that meditation can essentially rewire your brain.
This science challenges the common assumption that our levels of happiness, resilience, and kindness are set from birth. Many of us labor under the delusion that we're permanently stuck with all of the difficult parts of our personalities -- that we are "hot-tempered," or "shy," or "sad" -- and that these are fixed, immutable traits. We now know that many of the attributes we value most are, in fact, skills, which can be trained the same way you build your body in the gym.
