My only point was that we can't assume that *everyone* is going to enjoy doing *anything*. However, I would say that in most cases children start out, at the very least, nuetral. In other words, many small children have no idea what piano is, or what practicing an instrument will be like. Some of my most eager students have been those who did not ask for lessons but who were not against the idea either. Usually they develop a very positive attitude within the first two or three months.
By the way, adults beginners also have (usually) very little idea of what it means to practice an instrument.
Haha... I think if you effectively combined these two thoughts together you'd get;
Adult beginners (and many adults in general, too, I believe) have very little idea of how to practice.
Kids generally have an innate excitement about music, follow their instincts and actually practice very well when we let them.
Then, the adults who have no idea what it means to practice, quickly proceed to try to tell kids (who probably "practice" better just by instinct) "No don't do it like that!
This is the way you practice!"
