Try to eat blackberries "sadly." It's basically impossible. You have to try. I doubt you could eat a handful of anything that sweet and be sad about it. Blackberries just are not sad people food. Some songs have choruses that just sound fun. 'White Sky' by Vampire Weekend. Yes, they're weird but listen to the chorus. Can you even make that sound? I swear it's impossible to do that with out smiling. Try belting that out in your car, you can't be depressed about it. Also swimming. How can you swim and be sad? You have to concentrate on strokes, and you have to plan when you're going to breathe. You don't have time to be sad.
I think it it takes a lot of effort to be depressed. Just one hour of feeling sad and dark and you can feel like sleeping for eternity. Once you're stuck in it though, you have to use just as much effort to be happy. So I'm trying to find easy stuff like blackberries, laughing at myself, or swimming to make being happy a habit. It's supposed to be easy.
