the squeeky wheel gets the grease.
As the flint contains the spark, unknown to itself, which the steel alone can awaken to life, so adversity often reveals to us hidden gems, which prosperity or negligence would forever have hidden.
The unfortunate do not pity the unfortunate.
To enjoy a good reputation, give publicly, and steal privately.
People travel to learn; most of them before they start should learn to travel.
I do not know of a better cure for sorrow than to pity somebody else.
