I do hate to break it to you but it is increasingly less likely that you will take a photo that has never been taken before. Wether it is composition or subject matter there are few things that haven’t been taken photos of. So learn from what others have done. There are people who have been taking successful photos for years, and they are successful for a reason.
Study what they do, and mimic it. They are successful for a reason. For instance there is a reason that people take portraits in similar ways, they look best when shot like a pyramid. Just because the Mona Lisa is in a similar composition doesn’t mean that you can’t mimic it. Use the methods others use because they are successful for a reason.
Find a photojournalist that you admire, look at their work and see if there are ways that you can recreate their shots. Learn what they have done, and make your own work similar to theirs. Learn from experts, if they make a podcast listen to it, if they make tutorials watch it. Learn from what they have to offer and make your own work better.
