A person who wallows in such despair and self-pity would be well served by considering whether he is poisoned by envy, perhaps the envy of egalitarianism. To paraphrase Chesterton, at least the aristocrats of old had the satisfaction of feeling superior than others. The egalitarian man cuts down all those he fears are better than he is (typically by denying the qualities of others)!
The majority of our suffering, especially the spiritual and psychological variety, is our own doing. There are plenty of people born with all sorts of conditions who live happy lives because they've accepted the immutable and made the best of the cards they were dealt. If self-pity deserves anything, it is not compassion, but contempt.
Yeah or rather that man sees tbat often those who are better have counter-balanced that better by a marginal worse in other dimensions :)
Sometimes you are tired of grinding endlessly with little if anything to show for it, all because we threw a bad dice at birth.
