Hitting someone and being hit is a huge deal for most of us who suffer from chronic cases of nice girl disease.
The thing that kickboxing has taught me, though, is that this is life. You're going to get hit—emotionally and mentally. Not a week in my life goes by that something doesn't jolt me as much as a few punches to the gut: a disappointing work rejection or a disagreement with a family member or something as seemingly innocuous as my car needing to go to the repair shop. Kickboxing reminds me that I can take it.
