Shoot mundane things. Shoes in a corner. The face of your dog. A flower (MP Hunt really emphasized practicing the craft on flowers when I was getting started). Your neighborhood. Lines of fences, or walls, or utility poles. Even without our eyesight at a given time, the possibilities abound.
What inspired you to pick up a camera? For me, it was racing. I loved shooting race cars. Every year, I go play at the 24 hours of Daytona and then try to hit a few other races at some point. IT takes me back to the begining.
... Switch genres. If you photograph models, photograph people on the street. If you work in the studio, go do some landscapes. Put on a super-wide angle lens & move as close as you can. Lie on the floor & point your camera up. Climb a ladder & point your camera down.
... Photograph that which you are afraid to photograph.
... Remember, your failures are more educational than successes.
... Use images to make a story book, with a plot, a beginning, and an end.
... Or go to the museum & local art galleries.
... Go to the elementary school's holiday pageant.
... Go shopping for a thank-you gift for me, for getting you such great advice.
