One Habit I Wish I Didn't Have: Fingernail Biting

One habit I wish that I didn't have is my compulsively annoying ability to not stop biting my fingernails!  I have chewed my fingernails for years and I can't seem to stop!  Wearing nail polish, wearing acrillic nails...nothing stops me.  I guess my nails will always look like Frodo's.

Will it ever end?  I want my nails to be beautiful one day...but I can't stop biting them!
