A hook is a mechanic, not a sentence
There are maybe six things an opening line can do: ask a question the viewer answers in their head, make a claim they want to argue with, open a gap they need closed, put them inside a situation, lead with a number, or contradict something they believe.
Most people write the same one every time, usually a question, and their videos all open identically. This returns ten lines built on different levers on purpose, so you can hear which mechanic your subject actually suits rather than defaulting to the one you always use.
