If I were in a world of barter system, and were given a choice as to trade whatever I wish, I’d trade emotions. If I could, I would take all the sadness and depressions of the world, and give away my happiness in return. The only reason for making this uncommon trade is that making the world happy, and putting a biiiiigggg smile on the depressed faces is what I always have intended to do. And yes, making them smile would give me more happiness to overcome the pain of the world I took in exchange, so yes I’ll smile seeing them smile.
“The best way to cheer up is to try to cheer someone else up.” – Mark Twain
