每一次的演出都是一次新的挑战，我喜欢这种充满未知的感觉。
Every performance is a new challenge, and I love this feeling of uncertainty.
The higher your energy level, the more efficient your body. The more efficient your body, the better you feel and the more you will use your talent to produce outstanding results.
Millions saw the apple fall, but Newton asked why.
我不是因为快乐而歌唱，我歌唱是因为我快乐。
