PostEaseLead with the specific thing, not the setup
The instinct is to explain context first and get to the point after. A hook does the opposite. State the specific thing (the result, the mistake, the claim) and let context follow if it's needed at all. "I tried this for 30 days and stopped seeing results after day 12" earns more attention in one sentence than three sentences building up to the same fact would.
Be honest about what the rest of the content delivers
A hook that promises something the content doesn't deliver works exactly once per viewer. The next post from the same account gets scrolled past on reputation. The strongest hooks are specific and true. Write the honest version of the most interesting true thing about what you made, rather than a more dramatic version that isn't quite accurate.
Cut the first line you wrote
A common, almost mechanical fix: the real hook is often the second or third sentence you write, after the throat-clearing first one. Reread a draft and check whether the opening line could be deleted without losing anything. If it could, the hook was underneath it the whole time.
Test it against silence
Read the opening line out loud, alone, with no context. If it wouldn't make a stranger want to know what comes next, it isn't there yet. A hook has to work as a standalone sentence, not as a natural-sounding lead-in that only reads well once you already know what follows.
