One famous photographer said, "Your first 10,000 photos are your worst". I extend this statement, and say, "Your first 30,000 photos are your worst". By the time you take 30000 photos, you either give up photography or become a very good photographer. At the same time, if you do not have passion for photography, you cannot reach the 30000 photos milestone.
While, taking photos is the most direct way to learn photography, you can sharpen your eye for it in an involuntary way. Make yourself exposed to a lot of good photographs, and you will soon start developing the photographer's eye.
I would recommend you to add a bunch of photographers on Google+. When you are registering for Google+, the option comes up. If you have missed that step, search on "Google" for some shared circles on photography and add the circle to your own profile. Add as many photographers as you want. Soon you will see a pattern. Soon, you will discover what kind of photography you like. Follow them, copy-paste their style- it doesn't matter. Keep taking photos. Keep looking. In two years you will become a better photographer.
