Make it hard on yourself. Give yourself a handicap, but make it work.
Try this example: Limit yourself to one fixed lens.
Back story: Most camera systems these days give you a wide-range zoom that allows you to easily adjust the focal length from wide-angle to telephoto. This is convenient, too convenient. So how about forcing yourself to use just one fixed focal length lens, regardless of the circumstance.
Back in the day, many beginning photographers started with a camera and just one lens. Some photographers were happy to use one focal length for all their photos.
What do I mean by fixed lens? I mean a prime lens; in other words a lens with non-adjustable focal length, so not a ‘zoom lens’. Fill the frame as you see fit; you might need to walk around a bit to make your composition work.
So why not give it a try. Pick a lens, maybe a 50mm, but make it work.
In my examples, I was using a prime 90mm lens with my FujiFilm XT1.
I often think my best pictures go back to the 60s and 70s when I had mostly a fixed lens.
