motivation!

Hi everyone! I'm Karen. I'm 36 and have 2 children. I am looking for some motivation. I am 5' and 130. I am hoping to lose 15lbs...weight I've been carrying around with me from my pregnancies. I also just quit smoking about a month ago. I want to clean up my eating habits and not stray from working out. I am hoping to find MFP friends/support to help me stay on track. Thanks!!
