Yeah, the combination between Title, Image and First Line is what makes the hook a hook on steemit... But even making a good sounding title is hard, then what about a title that's good sounding and thought provoking at the same time?!
Another trick is make a surprise (or contradiction) between the title and the image, something that will make the reader think, why the the image has nothing to do with title...
It's a gamble since some people will think you're trying to trick them, or just not knowing what you're doing. But I love that type of gambles.
