In Episode 163, Billy Donnelly comes to terms with the fact that the idea of constantly being happy is impossible, and yet it is still an unattainable pursuit that human beings embark on constantly. He discusses the chemical reactions in our brains that result from moments of happiness and how they then become like a drug that we want more of. However, that sets us up with a hunger that can't be satisfied, no matter what thing we get that we're told will make us feel happy. He shares that he used to feel as if there was something wrong with him for not being able to be happy all the time, especially as others presented themselves as happy non-stop. But he has learned over time that people show you only what they want to see, and while he may have been feeling bad about himself assuming they were living awesome lives, that wasn't the case; they were just hiding their unhappiness better.
