My worst habit is smoking. I should definitely quit, but it is much easier said than done. I am putting myself at great risk smoking approximately a pack per day while also being on birth control, however low of a dose it is. I have been cutting back, which isn't nearly satisfying enough, but it is progress.
I don't make excuses and I know that if I truly wanted to quit, I would have done so. I acknowledge the fact that part of me still enjoys smoking.
