I Am Trying to Break My Bad Habits

Well maybe try one bad habit at a time, And I could be wrong but are a nervous person because if you are well that's why you bite your nails and smoke,

All things in moderation.
Well, that applies to smoking. With nails you can only bite them so far, right? :)

You're right that's time to break those two bad habits...

Good luck .. .. it took many times but I finly quit smoking .. .. keep after it .. .. ..
