I am a nail biter and have been since I was a kid. I notice that I do it most often when I am nervous or worried about something. About the only time I do not bite or pick at my nails is when I have just freshly polished them. I can resist when my nails look pretty with a fresh coat of polish...hence I try to keep up on my nail care. I do not paint my nails as often during the winter because of lack of time and motivation to do so. Come spring time, I like to have a fresh new look.
