Occasionally, a child walks into the studio who seems confident and can do the ballet exercises as if she's done them a thousand times. The fact is that all students are talented. There are levels or gradients of talent in every student.
Some students have to work harder than others.
In other words, talent can be taught and there is no limit to how much any student can achieve given the desire to do so. Above all I want my students to love dancing as I always have. If you are not sure if your child is in love with dancing, unsure if your child will ever blossom into a prima ballerina, just give it time. I find most students that do not really have interest drop out by the second or third week. What a waste of talent that would be.
