I like this exert from The Battle Hymn of the Tiger Mother:
'What Chinese parents understand is that nothing is fun until you're good at it. To get good at anything you have to work, and children on their own never want to work, which is why it is crucial to override their preferences. This often requires fortitude on the part of the parents because the child will resist; things are always hardest at the beginning, which is where Western parents tend to give up. But if done properly, the Chinese style produces a virtuous circle. Tenacious practice, practice, practice is crucial for excellence; rote repetition is underrated in America. Once a child starts to excel at something - whether it's math, piano, pitching or ballet - he or she gets praise, admiration and satisfaction. This builds confidence and makes the once not-fun activity fun. This in tun makes it easier for the parent to get the child to work even more'.
