to filcras :
if you like to read photography literature (books or magazine), you can chose based on what you find it is intereting to you, the photos (with descripsion of it) which are unique and looks so different and attract your attention. Right now there are quite many photography books and magazine, you can choose based on what you prefer. Just "take the major points" of what have been writen at the book / magazine, the rest (some minor things) you can develop your self ;p
if you dont mind, i want to share some points based on what i think it is good to develop your photography (pardon me if there is something not so ideal):
1. Creatifity and originality
you can step by step continually develop your own style which you think it is good and worthed. you can explore and enhace your creatifity and no need to worry so much about other things. Trial and error some times will teach us some good lesson. try to make your photo based on your style and your own perception.......and make it as your own originality that will make the photos more looks like taken by your own shot, not by others (this will be takes time)
2. Keep on exploring and learning along your Photography Journey.
Give more time and please never stop to explore and to learn anything about photography that you like. As a journey, it will lead to you to the next point / step to the new thing.....you can find something new there, you can get very usefull experience and ofcourse you can alway enrich you photography skill and perception ;p Dont be shy to try this and that (from A to Z) while you doing shoting, also try to shoot from different time (early morning, day time, afternoon, evening, night, cloudy day, raining day, etc), shoot from different angle and with different framing, etc including see more photos which taken by other photographers from different perspectives. Dont limit your own mind and your possibility, make it flows freely ;p
3. Doing all those things happily.
It is important and really make a big different if you can make your shooting times become something that you enjoy, you are happy while doing that. If you are happy, it will be easier for you to maintain the extra spirit (not easily give up, not lazy to shoot something difficult, you become dare to shot all out although it will take an extra time, extra energy, etc). and also if you are happy in doing photography, many things will flow and come out easily, your creatifity, your possibility to find something new and interesting and ofcourse you will become "healtier in photography" (means you are not stress while facing the photo session, no need to worried about many things, not boring doing shooting, etc).
