It is very importat for emotional wellbeing to have a creative activity.  Depending on personal tastes, this can be any of the arts, like painting, sculpture, writing, music or dancing, but it can also be anything else, anything from cooking to collecting stamps or building models.  It really doesn’t matter what activity you do, what matters is that is is really pleasant for you.  That way, not only will you have an enjoyable activity to do when you are sad or depressed, but it will help you produce endorphines, which not only make you happy, but they also mitigate pain.  Besides, a pleasurable activity gives purpose to life and it is something that we leave for posterity, something positive to be remembered by our descendants.
