训练并非易事，但我坚持不懈。

Training wasn't easy, but I kept going.

但我很快开始单纯地信任和喜爱我在玻璃上看到的东西：坚持不懈、信任和优雅。

I soon came to simply trust and love what I saw in the glass: persistence, trust, grace.

但我没准备放弃，因为我相信，如果坚持不懈，总有一天好运会降临在我们身上。

I was not prepared to give up, however, as I believed that one day, if we persevered, luck would fall upon us again.
