Why does it take me getting mad, for me to get off my a**?

I was out with friends this weekend and accidently bumped into a girl who was seated behind where I was standing. It was a small bump - I didn't realize she was there. I immediately turned to her and apologized for bumping into her. Before I could get my apology out and before she turned around to see me, she said, "OMG you have a huge a**!". My jaw immediately dropped.. stunned at her rudeness! I apologized again and then she said, "Oh, your actually okay." - Trying to take back her initial statement with a couple of retraction comments. From my point of view - the damage had been done. Still can't get that comment out of my head. Maybe it wouldn't have hit me so hard if I hadn't already been regretting and feeling the stress of not having worked out consistently in about a year. I have always loved working out and being fit, but life has happened and with the pressure of all the time obligations I've had, the exercise was cut out of my schedule. Anyway, I had been wanting to get back on the treadmill to get myself active again and tone up the bod, but the motivation was difficult to find. Well....I guess I got that through a very painful comment, whether she meant it or not. After the kiddos got on their buses and I finished payroll and a couple other priority projects, I jumped on the treadmill and started running. It felt great! So now I have my motivation and I got started! I hope to never hear those words again in my life!  So... in the spirit of a post I put on my facebook page... A successful woman is one who can build a firm foundation with the bricks others have thrown at her.  I also added, "A strong woman will thank them for the bricks".... I am thankful for the rude girl and her hurtful comment, as it was the motivation I needed to get my "huge a**" active again. I just had to get mad enough to put my physical health back to priority level.
