This will be a good resource for people who are new to mindfulness and emotional regulation and not experiencing severe crises or dealing with severe trauma. At times it felt a bit like victim blaming and like toxic positivity, especially when discussing Viktor Frankl with that sort of message that if Frankl can find peace and meaning in a concentration camp then you should be able to with whatever you’ve endured. (Those who have really researched Frankl know there was a lot that was changed and left out of his narrative and his was a very complicated story in reality, but even so, it’s a message that a lot of people point out has been twisted from what Frankl called tragic optimism.) The bulk of the book is tools to reframe situations and mindsets. Brackett talks about lot about his own issues in childhood like bad bullying but it may be a harder read for survivors of serious abuse, grief and trauma to simply change their valid, persistent, debilitating feelings.
