2. Nail Biting
Biting your nails isn't as unhealthy a habit as snacking, but it's still a bad one. It's embarrassing to have ragged, chewed nails. And since it's a habit associated with anxiety, it can feel like people learn all about your mental state just by glancing at your hands.
No matter what the reason, if procrastinating is a problem in your life, you have to be proactive. Set clear goals, with rewards if necessary, and imagine how great you'll feel when you finally complete that project with time to spare.
4. Gum Snapping
Learning how to blow bubbles is one of those childhood rites of passage, like whistling or riding a bike. But by the time we reach adulthood, we're not normally chewing bubble gum, but the kind that freshens breath. That gum isn't ideal for blowing bubbles, so some people resort to snapping, or popping it instead.
