Slate interviewed Vincent Kartheiser, the actor who plays Pete Campbell on Mad Men. This episode has been out for a couple of weeks old, but I thought it was neat.
Slate: He’s a man of ambition, but he seems to get more unhappy the more he achieves. He’s achieved many of his goals—Trudy had the baby, he got a bigger office, he’s dominating Roger—but he seems to get crabbier by the week. Do you understand why he’s so unhappy?
Kartheiser: With success comes a level of sadness. You think, “I’ll reach this goal, and then I’ll feel a sense of completeness, of wholeness. I’ll feel that I have accomplished something. I will see myself as a worthy man.” And it doesn’t really exist.
