I think that a good person can sometimes do wrong out of ignorance or weakness or wrong thinking, but when hard times come, the goodness wins out after all. And a bad person can often seem good and trustworthy for a long time, but when hard times come, the evil in him gets revealed.
Actual happiness always looks pretty squalid in comparison with the overcompensations for misery. And, of course, stability isn't nearly so spectacular as instability. And being contented has none of the glamour of a good fight against misfortune, none of the picturesqueness of a struggle with temptation, or a fatal overthrow by passion or doubt. Happiness is never grand.
