Plaza Statement - Leave a positive opinion behind should be your strategy as well.
When starting to dance competitions on an international level consider than that most of the judges often don't know who you are and what your level of dancing is. But they will keep a sharp eyeon your performance!! Don 't start to early with international competitions, make sure your dancing is on the required level for that. Consider that on competitions the Judges are building up (unaware) from each couple they see a positive or negative opinion in their mind.
