Notice in this photo how all lines converge to a single point. That's how one-point perspective works.
Take a look at how artist Joe Paquet uses this device.

Just like they do with all of nature's organizing systems, artists find intriguing ways to employ one-point perspective. Look at how Paquet found it and made it work here.

He's a bit more subtle in this next piece.

And he does a similar thing here.
One-point perspective is not so much a composition principle as a structural device that can guarantee an artist both an eye path and correct visual perspective. Sometimes a scene will contain exactly what you need; at other times the artist will make a few adjustments to enable the images to fall within the structural intention.
Probably one of the most ingenious one-point perspective painting ever was done more than 600 years ago: Leonardo da Vinci's "Last Supper."
Have a fun weekend.
