Another trick to become original:
1) Chose a photographer you like the work from a conceptual point of view (technical is possible too, but not essential). Stick with his/her work, and re-shoot the most of his/hers photographs, some even repeatedly. What’s important in this autodidactic learning is to guess what your virtual mentor felt and thought when he/she took the picture you’re re-shooting. Get infused by his feelings and thoughts.
2) At one moment, you’ll feel a strong need to leave your mentor and to be yourself. At that point there are two options:
2a) "The 180° turn": hate to imitate his/her work and want to be yourself immediately. At this time, you have some chances to discover a new point of view, but these chances are weak, and there is the risk to collapse if you find no original way.
2b) "The development": you feel no pressure to become original, but you discover, by surprise, that you could see one of your mentor’s photographs differently. Next day you'll see different another photograph, and next day two others or more. In between a week or a month, you'll feel that your brain is building a system, an original one, helping you to see and express yourself differently. Don't check if you made a discovery or you just rediscovered – leave it for later. What is important at this stage is to leave your new conceptual system to mature. During this period, it is very possible and normal to change your style once, twice, or even three times (don’t do it more). In one of these new styles, you'll find yourself as an original, mature (or almost) artist. Now you can check if you really are original or not – chances to be are now about 99.9% (I would say).
Obviously, I recommend the 1+2b option, because I’ve seen it at work (not with me). As for me, years ago and not in photography, I made the mistake to take the 1+2a way, and finished badly.
