That X factor

You ever do the same thing over and over and over?  It's engrained in your soul it's a part of your personality.  It bugs the hell out of you, and probably others.  We all have that.  That one thing we want to change.  Every new year, new month, new season, new relationship, maybe even new day, we tell ourselves, "this is the day to stop",  stop self sabotaging.  That's all you are doing.  I do it, you do it, we all do it.  We all rationalize why we do it.  For me, my little quirk that I would erase out of my behavior is emotion based.  That silly metaphorical tantrum I throw when things don't go my way, or I feel hurt, or ignored.  That one thing I know is a bad idea, I know will make everything worse, and I know I will regret.  I call it my X factor. This is because I am 99% sure this behavior is written into my personality by the fact that I am XX, female, a girl.  Maybe this is true.  Maybe I am just a bitch.  I also call it my X factor because, ask any of my exes... it was probably the straw that broke the camels back.  We all have one.  What's your X factor?
