Pay no attention to street photography rules. Shoot intuitively and live with your photographs for a while before showing them to the world. Your work will be better.
Buy a 35mm disposable camera and hit the streets for an afternoon. The freedom from camera settings will be exciting. 27 frames with nothing to think about but subject and framing. Even the framing is guesswork. Have fun!
Print your photographs. Get yourself off the computer screen. Make physical prints. Not only are they a safer bet for archiving your treasured images, but also they will resonate with you differently. Make a thing, not just a bunch of 1s and 0s.
Buy a simple, lightweight, fast and versatile camera for street photography. Look for a lens that can go as wide as 28mm and as long as 70mm. This will allow you to capture every kind of situation you might encounter.
Broaden your arsenal of knowledge beyond street photography. Read and learn about art, cinema, literature and pop culture. Become visually literate and liberally educated. It will show in your work much more clearly than you imagine
