Do something radical and cheap.
Pinhole, anamorph with a cylinder, make a box camera from foamcore, etc.
You get a totally different outlook on DOF, sharpness, time lapse, multiple exposure, multiple aperture, etc, etc.
Then go back to a manufactured camera with an altered experience. I did a 2-3 year pinhole hermitage, left 4x5 Graflexes etc on the shelf. I'm back to lens & RF stuff now, excited about glass too, but picked up a sense of perspective from pinhole I never had as an 'appliance' camera operator (I don't call myself a photographer yet).
