When it's your own fault, things hurt worse than when someone else is to blame.
It is a painful thing to look at your own trouble and know that you yourself and no one else has made it.
The evil done by oneself, self-begotten, self-bred, crushes the foolish, as a diamond breaks a precious stone.
Hell is the special pain that dwells in that loss which you yourself have caused
Most of our miseries we bring on ourselves. And they're the sum of our own stupidity.
A consciousness of misfortunes arising from a man's own misconduct aggravates their bitterness.
It makes sense that no one else can cause you pain. That's your job.
Humanity is fortunate, because no man is unhappy except by his own fault.
