Interest is a kind of power that can drive people learn actively and happily. And it also makes learning more effective and efficiently.

I really appreciate the opinion. I begin to be crazy about English when I was a little boy. And I got interested in foreign culture and customs in particular to meet my curiosity. I read English stories, listened to English songs and watched English films on every day, all of that even seemed to be the “meal” of my daily life — As the result, I always did very well in English exams.

In a word，interesting is the key to success. Anyone who are interested in something will devote himself to them.
