Stretching the Limits

So, I consider myself to be a pretty fit guy. I exercise every day, I push my limits, expand my comfort zone. Then a couple of weeks ago a friend of mine started teaching me Yoga. I've done yoga before, but this is one on one. As in you can't hide. In just a couple weeks it's exposing what still Can be improved on with my body and mind that I wasn't aware of before. And, of course the only way I could know that is by doing something I haven't done before or to do it in a different way. This can be scary, uncomfortable, even painful. As I keep learning, when I'm willing to stretch my limits, I realize that I really don't have any.
