Ganesh because he's the god of learning and wisdom, and Hindus invoke him for success, also, they call him the remover of obstacles, and Ive always been drawn to the image, found out what it meant, and knew I wanted it.
It symbolizes kin what I want and where I am right now.
And front of my shoulder, not on my arm nor on my chest, it'd be covered even by a thick tank top, or a short sleeve would more than cover it
