Why do I keep letting things get away from me?

I came to the conclusion the other day that I need to get over myself and get on with my life and become who I want.  4 years ago I was thin, 160 pounds.  I was still unhealthy due to smoking and increasily frequent bouts of bronchitis that would eventually nearly kill me.  I knew I had to quit smoking because the effects on my health were not worth it.  I quit and FINALLY I could breathe and start living.  One of the proudest things I did was push a stroller all over the zoo for an entire day without getting winded.  I was thrilled I could do that and feel good while doing it.  Then the pounds started to pack on and I became complacent, a state of mind that I’ve remained okay with until this week.  I realized that much like the smoking my weight has been holding me back from living.  I’m still unhealthy and only I can change that.  Guess what?  I’m ready so bring it on.
