Spontaneity could explain low-level sadness

An often overlooked but essential ingredient in a good life is spontaneity. Without it, we may suffer from an excess of orderliness, caution and rigidity. We haven't danced in a long while.

A more spontaneous life means that we will be more impulsive in expressing emotion and thoughts. In our work, we might embark on a potentially life-changing initiative sooner than we imagined. In our leisure time, we might start to write a collection of recipes or poems.
