Not long ago I wrote about being successful at CrossFit and what would it take.   And yes, you have to work hard, but that is only 1/3 of the equation.  The other 2/3 depend on your nutrition and your state of mind.  “The greatest adaptation to CrossFit takes place right here: in our mind,” Greg Amundson says, paraphrasing CrossFit Founder and CEO Greg Glassman. “Our words become real,” therefore if you’re drowning in negative self-talk and self-pity, you’re not going to optimize performance. But if you speak in positive terms and maintain the right frame of mind, many great things are possible
