“No, wait … I’ll tell you something,” said Zaphod. “I freewheel a lot. I get an idea to do something, and, hey, why not, I do it. I reckon I’ll become President of the Galaxy, and it just happens, it’s easy. I decide to steal this ship. I decide to look for Magrathea, and it all just happens. Yeah, I work out how it can best be done, right, but it always works out. It’s like having a Galacticredit card which keeps on working though you never send off the cheques. And then whenever I stop and think – why did I want to do something? – how did I work out how to do it? – I get a very strong desire just to stop thinking about it. Like I have now. It’s a big effort to talk about it.”
