Starting TOO Early

Generally speaking, now is really early for starting this process. Some people were asking questions in preparation for the 2013 application when it was January @_@ I don't think anyone recommends starting this early because there are a lot of cons on top of those pros.

Pros:
-can ask for LoR and not be SO concerned about not getting them in time
-tons of time for editing and opinions on the SoP
-can look into volunteer work or jobs that are applicable to JET
-just enjoy thinking about JET too much :P

Cons:
-stress too early and you'll never make it all those months until the actual application process
-too much writing, drafting, editing of your SoP can make you sound robotic or insincere
-the paperwork is not out yet, so anything you look at this early is not what you will be using for your actual application
-thinking too much can add to the stress; you can start thinking about too much stuff that you could do to be better, but be unable to do said things, and start feeling not good enough for the program
-your family will kill you before you get to apply because they don't want to hear about it anymore (or maybe that's just me)

Obviously, I don't think that starting to think about JET this early is SO bad or I wouldn't be doing it. There is a definite danger in thinking so far ahead, though; if I could just let it go and stop thinking about JET for the next three of four months, I would, but I can't, so I don't. So, don't stress now, if you are like me and can't forget it for a few months, do things that you CAN do, not worry about things that aren't worth the time yet.
