Julie would like to walk like a tightrope walker on a high tightrope. Of course, she overestimates her abilities! She also overestimates them in the comical adventure as she takes on the mission of taming a horse that even her master has difficulty mastering. With this experience, she will understand that it is not enough to want to succeed in something; it also takes time and practice (without skipping a step) before becoming skilled in something.
