An editorial interpretation.
Success comes with an odd loneliness in this wry take. Getting there is supposedly the hard bit, yet the speaker says the real difficulty is finding anyone who is honestly glad about it. It hints at envy and awkwardness hiding behind congratulations, delivered with a comic sigh.
