A man who counts his gains with eager joy55 finds all his thoughts turn anxious and despondent the day reverses make him face a loss; - Dante Alighieri

"Why doth thy mind so occupy itself,"
The Master said, "that thou thy pace dost slacken?
What matter it to thee what here is whispered?
Come after me, and let the people talk;
Stand like a steadfast tower, that never wags
Its top for all the blowing of the winds;
For evermore the man in whom is springing
Thought upon thought, removes from him the mark,
Because the force of one the other weakens."

Purgatorio V: 10-18

No greater grief than to remember days
Of joy, when mis'ry is at hand.

It follows, then, that the only way to get into Hell is to insist upon it. One must deliberately exclude himself from grace by hardening his heart against it. Hell is what the damned have actively and insistently wished for.
