Discourse: 1) As much as you want to, resist the urge to pluck your nail polish. This will weaken them and may cause an infection. 2) If you want your nail polish to last, don't bang your nails on any surface. This can also weaken them and spoil the nail polish. 3) To avoid breaking, hurting, or weakening your nails, don't use them as tools. You'd be better off using the correct tool!
