Do you have a habit that you like to break?

I really want to break my nail biting habit for a long time now. It's not just my finger nails that I'm biting off, I also bite off the skin around them until they start to bleed. I try to be aware of when I start to bite my nails so that I could stop myself from doing so but the only time I realize that I'm biting my nails off is when they start to hurt. I really want to get rid of this habit as it is really painful and I'm embarrassed to even look at my fingers. I try to find alternative things to bite like the caps off of my ballpoint pens, or the plastic straws that comes with most drinks, so that I won't chew my fingers off so much. Chewing gum also helps me but after chewing the same gum for hours on end, my jaw starts to act up and hurt, and I can't chew gum during class hours nor do I carry gum with me all the time. This habit is just saddening me. :(

on my experience I did have like I want to break the way I study with laziness. when I was in college I'm so bored and when I met a girl that you know... makes my heart beat! I realize how lazy I was and what I know she is a very bright girl and I don't want my laziness be blame for me.

I have a habit to speak to loud and I have to control my mind.,

I have a habit of thinking too much.I always want everyone near me to be happy and full of praises for me and in that process I lose lots of mental peace.My hubby is very practical man and has taught me to become bold and carefree. But I Think I should improve my habit of thinking and doing self torture.I have improved a lot and now I dont bother for unnecessary things.

I like reading novels, this is a hobby?Sometimes the delay in the study, inner self-blame. I want to give it up, but could not bear.

I have a habit of drinking soft drinks and i still cant stop it.Hope I do it soon.
