Self inventories were never much of a thing when I was growing up. I can see the benefit and I think if implemented correctly, they could have huge benefits. I wish there are things I had realized about myself earlier and worked to fix them. I feel like now I am fighting a uphill battle with some of them.
I think that this lack of reflection when young, has led to an explosion in "mental health" now, but they are often doing more harm than good.
