The former "Friends" star says fulfillment of his career ambitions have failed to lift his bleak outlook on life, and he he'll only find true happiness when he becomes a father, the World Entertainment News Network reported Tuesday.
"It's a question that I ask myself a lot. I think I have moments of happiness, but I'm not generally happy," he said.
"I distract myself with work, rather than finding a kind of peace or happiness, which still eludes me. Basically, I don't think I'll truly be happy until I'm a father and a husband. There's a part of me that thinks, did the celebrity thing, did the entertainment thing, done plays, done TV, done film -- done it."
