Question of the day. How much does an individual part of a story, effect the whole product for you? 

Can a couple really bad sentences make you stop reading something and kill your desire to even finish it? People say the first lines make all the difference. Is that the case for you? Can something really hook you within the first bit? Or is the first sentence such a slog that you can't imagine reading the rest? Because I feel like my brain is overly nitpicky at times. But when I read nearly every single line and go, "You probably could have found a way to shorten what you just said." I genuinely feel like my time is being wasted, like I'm reading someone expanding an essay word count for class, rather than expanding a narrative, action, character or emotion being conveyed.
