It's the Habit I Just Can't Kick 1:06 PM I have got to give up biting my nails, especially when they happen to be painted. I nervously chomp away at my fingertips for no reason and start to choke on the chips of nail and nail polish. I have been doing this since I was 4 years old. I always considered it just some nervous tick that I do. I used to also suck on the tips on my hair, but promptly stopped when I started to add hair spray to my hair routine. What kind of odd habits do you all have? Or which ones did you used to have?
