How to draw storyboards in a quick observation setting?

I'm looking for the techniques of drawing basic shapes to record objects and actions in a field setting. A simple storyboard with outline figures would be my end goal.

Print off a set of squares with room for a couple of lines of writing underneath, then have a few of these pages ready for when needed. Use stick figures or blobs if you want, they're more for your use and general description. Arrows are good for action aswell, quickly and roughly describe in words below to help remind you later... Hope that helps, I usually draw up storyboards from my mind when planning things so you might have to adapt it a bit, there's no real standard for them but they're good for drafting up ideas and also for the likes of remembering stuff later on.
