The fountain of beauty is the one, namely the core of your heart.
All the learners ardently aim to speak elegant English through receiving lessons here at English Hills, Ginza, Tokyo, Japan. Usually, people in general just try to obtain English knowledge to satisfy greed for knowledge in the process to learn English. However, it is not a beautiful way for you to learn and (in the future) master elegant English at all.
The truth is that you must polish "the core of your heart" in addition to obtain English knowledge. Because as I mentioned earlier, the core of your heart performs as the fountain of your beauty.
The beauty engenders the elegance in the core of your heart to express what you wish to tell elegantly from your heart.
