Some components of a thriving friendship are honesty, naturalness, thoughtfulness, some common interests.

保持友谊长青的要素：诚实、朴实自然、体贴和共同的兴趣。

——爱默生

Only through experience of trial and suffering can the soul be strengthened, vision cleared, ambition inspired, and success achieved.

只有历经艰难困苦的磨炼才能强化心灵、开阔视野、振奋人心，从而成功。

——海伦·凯勒（Helen Keller）
