I woke up this morning and my hamstrings were sore from walking all over New York City and the MOMA yesterday. I thought I was in good shape. It turns out that I wasn't used to walking that much on concrete. Every once in a while, it's good to push your limits.  It's also good to flex some new muscles, especially in sales.  It may hurt a little bit, but in a good way.

You have probably been selling the same way for a while. That's great if you are seeing the results you want. However, if you are not seeing the results you want perhaps should try a new exercise - and flex some new muscles.
