流金岁月：

有情饮水饱了 if you have love, you don’t want for anything else

, that’s all you need

利欲熏心 blinded by greed, obsessed with desire for gain

冷暖自知self-awareness comes from within，to know best by personal experience

寄人篱下

他想尽快找个工作, 摆脱寄人篱下的生活。
He was most anxious to find a job so as not to have to depend on others.

学如逆水行舟, 不进则退。
Learning is like sailing against the current: either you keep moving ahead or you fall behind.
