I'm in a bind as its my first attempt at a longer story. I've never had a problem keeping hold of a reader in a short piece because you can hit them with plot points and foreshadowing in a much smaller space. This slow-burn writing isn't coming easy, I feel like I need to get to the next explosion of interest as quickly as possible and my motivation suffers for it. I've had a plot in mind for a long time, with many major plot-points organised in my head and the core of the story sorted, but how I fill the weeks/months/years between these moments is lost on me. I want my story to run from the protagonist being a child at school (when the idea that the world is not such a good place seeps in) to the moment he finally resolves his story when I estimate he would be in his late 20s. So specifically: How do I go about stretching out these interesting parts and filling in the gaps between them without being boring or boring myself?
