I just thought it was bizarre that people's minds work so differently.

I'm often driven by the clue. I have an idea of how I want to present the information and then find a place that works. Like this one, for example:

I had a couple dozen verses printed out that I carried around for six months till I found a location that had the right elements. The last thing is thinking of a stamp image that fits the theme.
