Finger nail biting is one the bad habits that bothers me most. When I'm concentrating on my work I can suddenly find myself biting nails. My focus started from my business moves to biting my nail so this habit makes me less productive. What's worse about this habit is that it's like a vicious cycle. Once I cut my nail twisted while biting, its shape disturbs me to bite more to make proper shape. Some kind of obsession to balanced form is triggered. Additionally, if the shape of nail is unrecoverable, that very fact interrupts me more heavily. As in these various aspects, biting fingernail is the most obstructive bad habit to me.

Hello, Ms. WooIn! It’s very relatable in the way you described how this habit can creep in even when you’re focused on something else. The way you link the cycle of focus shifting to the obsession with correcting your nails is insightful. It's like you’ve captured the frustrating, almost compulsive nature of the habit, and you conveyed that struggle effectively.
