I would. I think, with time, I'd get used to the idea of being charged with the safety of the world. Especially if I could start off with Airbending. I greatly value agility, dexterity and flexibility.
And for my own special airbending technique to qualify me as a master, I'd try to become the first master of SOUNDBENDING. Sonic Scream and other sonic attacks, sonic barrier/wall, sonic-repulsion flight, and sound cancellation (for inaudible, ninja-like movement), etc.
Either that or I'd take a clue from the first Bloodbending master, Hama, and invent BREATHBENDING. Hold my breath longer (even indefinitely), vortex-like inhalation, gale-force exhalation, and even stealing the breath of foes to suffocate them, or expanding their breath to explode their lungs.
