I think this is when most people give up on their stories. They come out of college wanting to change the world, wanting to get married, wanting to have kids and change the way people buy office supplies. But they get into the middle and discover it was harder than they thought. They can't see the distant shore anymore, and they wonder if their paddling is moving them forward. None of the trees behind them are getting smaller and none of the trees ahead are getting bigger. They take it out on their spouses, and they go looking for an easier story.
