Vincent Van Gogh used to eat yellow paint because he thought it would get the happiness inside him. Many people thought he was mad and stupid for doing so because the paint was toxic, never mind that it was obvious that eating paint couldn’t possibly have any direct correlation to one’s happiness, but I never saw that.
If you were so unhappy that even the maddest ideas could possibly work, like painting the walls of your internal organs yellow, then you are going to do it. It’s really no different than falling in love or taking drugs. There is a greater risk of getting your heart broken or overdosing, but people still do it everyday because there was always that chance it could make things better.
Everyone has their own yellow paint.
