I feel really strongly that doing something - anything - where we get into the flow, and focus on it closely is really good for mental health, wellbeing generally and happiness. Running, cooking, pottery, crochet. It doesn't matter so long as it absorbs your attention and you can feel yourself improving - for no purpose but your own pleasure.
