All programmers are optimists

All programmers are optimists. Perhaps this modern sorcery especially attracts
those who believe in happy endings and fairy godmothers. Perhaps the hundred
of nitty frustrations drive away all but those who habitually focus on the end
goal. Perhaps it is merely that computers are young, programmers are younger,
and the young are always optimists.
