What’s the one tip you’d give yourself starting out as a photographer?

There are many tips that can help you improve your photography skills, but if I had to choose one, I would say: Practice, practice, practice. Photography is a skill that requires constant learning and experimentation. You can read all the books and articles you want, but nothing beats actually going out and taking photos. The more you shoot, the more you will discover what works and what doesn’t, what you like and what you don’t, and what makes your photos stand out. Practice will also help you master your camera settings, your composition, and your post-processing. As the famous photographer Henri Cartier-Bresson said, “Your first 10,000 photographs are your worst.” So don’t be afraid to make mistakes, try new things, and have fun with your camera. Practice is the best way to learn and grow as a photographer.

This is all very well but I seem to be forever sorting my photos from miscellaneous image files from work in other folders.  There must be a way of selecting what pictures you want to appear in your photos... Info - Onedrive are working on this feature.

Whenever I was asked by people who wanted to get started at photography I would give them two pieces of advice. 

1. Experience is the best teacher, take as many photos as you can! I'm completely self thought myself and that's really down to keeping my camera with me at all times and taking photos constantly. 
2. Don't buy a new camera until you've reached your limit with what you can do with your current camera or phone. People are always believing that they need expensive cameras to take good photos but some of my favourite photos were taken on my phone. Practice with what you have. When you reach a point where you can't take the type of photos you want, and only then, upgrade to a camera that suits your needs. I used my starter DSLR for years as a professional before finally upgrading. Trust me, most people won't notice the difference.
