Thinking about the worst habit one has is definitely hard. Most of the time you don’t really notice a habit until its pointed out to you. I guess the only habit I have that I don’t really like is cracking my fingers even my toes. Ive been doing it for so long that now if I don’t crack them they hurt. I once read somewhere that if you crack your fingers they become long and ugly I never really looked into this myth but I’m starting to believe it.
