Sometimes I don't usually have any ideas coming out of my head when I am writing a story, I just let my characters have a personality of their own as if they are really living people. Then I just get something out of their behavior about how they will act in given scenario or situation.

We do get writers block at times and also sometimes an idea just appears out of nowhere and we are totally inspired like a whole new story comes up. It's best to write it down and take down notes about the Idea before we forget it. On a notebook or anything we could write on, either through pen and pencil.

I like writing down ideas I come up to make sure I don't have to keep remembering them until I write it on my manuscript with a risk of forgetting. It is a good therapy to write down notes from ideas that came up all of sudden. It is like a puzzle piece you have to collect and then fit them properly to form a bigger picture of a puzzle.
