habit
When referring to a personal routine, "habit" is usually a countable noun. You can have "a bad habit" or "many good habits." Be careful not to confuse it with "custom." A habit is typically something one person does regularly, while a custom is something a whole society or group of people does. In the context of clothing (religious or riding), it refers to a specific set of garments and is always used as a countable noun.

Stop padding your reports with buzzwords. It's becoming a bad habit.
David Smith
My bad. I'll pivot to more granular data next time.

Victoria is bluntly correcting David's tendency to use corporate jargon ('padding reports') to hide a lack of substance. David responds with 'My bad' (slang for 'my mistake') and ironically uses another buzzword ('pivot') while trying to apologize, highlighting his character trait.
