You know that point in a plot where the main character reaches a point of no return? He or she can't go back to the good ole' life they had. They can't undo whatever decisions they made that got them into the mess they're in now. Granted, it's not all the main character's fault because there are always external forces at play, things that are completely outside of the main character's control. But the main character is irrevocably changed none the less, and as they reach that final push and look down from the pinnacle of Mt. Climax, the world is spread before them, miniaturized. The pieces of their past, the foreshadowing, the supporting characters, the chain of minor and major conflicts spread out like a criss-crossing trans-continental rail road track- it's all mapped out so clear.
Yup, that's where I'm at right now in real life. I know that once I make it past the last turning point and am comfortably settled in the after math, I should be able to look back and say, "Man, that's some good writing material."
