Cathal Morrow, an author, could teach us all a lesson. He has spent the past year living under philosopher Immanuel Kant's notion that lying is always morally wrong, and claims to have told the truth for 12 months, during which he told his mother she was boring and his wife that her posterior looked plump. Now he's onto his next venture: to live for a year without unhappiness, in an attempt to prove happiness is merely a state of mind.

How is he funding it? Well, that's where the private equity money comes in.
