Researchers at Harvard, Yale and MIT have found evidence that you are what you think.

"Our data suggest that meditation practice can promote cortical plasticity in adults in areas important for cognitive and emotional processing and well-being," says Sara Lazar, leader of the study and a psychologist at Harvard Medical School. "These findings are consistent with other studies that demonstrated increased thickness of music areas in the brains of musicians, and visual and motor areas in the brains of jugglers. In other words, the structure of an adult brain can change in response to repeated practice."

And about the benefits of meditation:

Facing an important deadline, people tend to worry about what will happen if they miss it, or if the end product will be good enough to suit the boss. You can drive yourself crazy with unproductive "what if" worry. "If, instead, you focus on the present moment, on what needs to be done and what is happening right now, then much of the feeling of stress goes away," Lazar says. "Feelings become less obstructive and more motivational."

There is speculation that meditation may even slow or reverse aging because it "counteracts the natural thinning of the thinking surface of the brain."
I am convinced that meditation can only improve trading and so I am now going to try to do it every day. For those of you who have never meditated before, this is a great place to start.
