Not just studying the technicalities of photography, of exposure, of light, of your camera and other gear. Study other photographers and artists, their techniques and images, and the visual languages they use.
2. Intentional Practise
Practise taking pictures and processing them, but also be intentional about what you practice, at least some of the time. Challenge yourself (or find someone that will), experiment, and don't just keep repeating what you already know you can do well.
3. Gear Gratitude
There will always be a new camera body or lens or tripod that's somehow better than yours. But having that new piece of gear won't make you a better photographer. Be glad with what you have, and learn how to get the very best from it.
What I mean by visioning is thinking about the images that you want to take. Not just planning details like location and time, but what you want to convey in your images. What's the story, or mood, or feeling? Browse other images, meditate, dream, listen to music - whatever works best for you. Get some ideas about how you want the images to look before you shoot them.
Write stuff down. Or type it if you prefer. I keep notes in the Day One journaling app on my iPad, but also keep a paper journal of notes before and after each photoshoot. If you want to get better at something, writing it down speeds up that process.
6. Be selective
I'm not particularly an advocate of taking less photos, but I do believe in the benefit of going after a particular image. If you have an idea for an image, don't be satisfied with your first attempt. Keep trying, change something, be fussy, make corrections. I'd rather have 1 great image than 50 average ones.
7. Stop comparing
There is always going to be someone with more followers, better gear, more experience and, lets face it, there will probably always be someone taking better photos. It doesn't matter. You're not competing with every photographer on the planet. If you like their work then figure out why and learn from it. Let them do their thing, and get on with yours.
