First, I would so be a fire bender but I can choose avatar so that too. But think about it. Legend Of Kora is basically the same thing. There is a statue of Aang right in the middle of the water! Metal bending would be cool. What if you don't know how to control it? That would be bad!!
it is real. and heres some tips on how to! for Earthbending, pick up a rock and throw it. now that you mastered that, for Firebending you can get a lighter (if you can use one safely ) and use it. Airbending is easiest. just breathe out. last but not least, for Waterbending, turn on the faucet. you are now a full-fledged Avatar, with mastery over all the elements! :)
bending is real. i can water bend completely, fire bending training halfway (can almost completely control it), earth bending very little. i can barely lift a boulder. air, i haven't got to yet. im from the southern water tribe and have moved to the United States. you just have to believe you can bend and work very hard at it. keep on going and you will succeed one day. unless youre a non bender. i am very sorry for you then.
