Answer:
hey, that is a great question.
Explanation:
i think that for me it was when my 4 year old brother was eager to learn. He was determined to learn all the planets and how many moons they have. After he mastered that he started learning how to multiply!!! then i started teaching him how to play the piano. He learned so fast and can play very well for his age. he can play we wish you a merry Christmas with the right fingering and jingle bells. he can also sight read the notes.
Hope that you have a terrific day!!!!
