I'm a fan of Jillian Michaels on Facebook and she just posted this entry on her status...amen, sistah, amen.
Don't blame anyone or anything for your situation or problems. When you do that you are saying that you are powerless over your own life - which is utter crap. An empowering step to reclaiming your life is taking responsibility. Although life may deal you some bad hands, evaluating the choices you make in response to those hardships is critical in affecting an outcome that is more favorable to you.
Did I mention that I love Jillian?
