Sorry to interrupt, but this are very bad advices regarding healing. Keeping the circles big is absolutly not neccesairy - this is just a visual hint that the green or blue heal is getting closer to running off, it does not heal less or means anything beside this. Telling a new player to "always keep the circles big" will turn him into a healbot. Also the blue heal is a cone in front of you and you have to actually hit players with it, but you can cast the green one anywhere you want and it will hit your groupmember if they are not blackend out in your grouplist. With blue and big heals you can heal players you are not grouped with, with green only groupmember. Try this guide

and then just watch what happens if you use your heals, and take some time to learn timers, duration and debuffs.
While leveling you can just try what you would like to spec, when you start raiding and groups on 80 just ask a PoM you see heals and dpses good if he can give you some insight about healing specs, dps specs etc.
