Seriously, if you are going to make dancing your career here, it's really hard, just as hard as all the other artists, since this is a place who doesn't adore art that much. But really, if you have talent plus you are well-trained with certain recognized certificates/diplomas/degrees and some prizes/medals/trophies, you can still make a living; if you know people and you are willing to go partying around so as to keep in touch with those important people, you can even earn a decent living.
Speaking from my experience, dancing as a career surely requires you to take risk, so pursue it when you can still risk everything, don't wait until you are too mature to considerate every tiny bit- at that time you'll lose the courage to go after your dream.
