For too long we have focused on stress, and the concepts of "risk" "safety" and "worry."
This book makes the great point that most humans are actually pretty resilient, and by and large they handle life's stresses pretty well. When you look at things this way round the person with "stress" usually turns out to have a temporary strain and to be otherwise managing well. If they can map over their abilities from other areas of their life they usually find they can find a way to handle their current strain.
If you want mental health it makes great sense to focus on how to build up your resilience rather than on the neurotic avoidance of stress.
This book is an excellent description of why resilience is so useful, and of ways to bolster it. I recommend it as an antidote for, and as a necessary balance to, concepts of stress.
