I don’t believe in getting drunk. Or in dope. Or in taking a holiday for that matter. While all these offer good short-term benefits, their problem is just that – they are way too short-term. Once you’ve finished experiencing them, you’re back to square zero. No better off than you were before you undertook the experience. In a large number of cases (piled up work, hangover, etc.) you might even be significantly worse off.
Happiness needs to be sustainable, and the above mentioned methods don’t really guarantee that. It’s like putting a coat of white polish over your white canvas shoes. The dirt remains, only gets covered. You run a few hundred meters and the dirt is there for all to see. Or you can think about it as using a band aid for a really bad injury. Just covers up the surface.
