Post traumatic Growth. New studies show that 90% of people thrive after challenges. Post traumatic growth isn't getting back to where you were before, it's about thriving beyond that point - achieving heightened states of joy and awareness.
It's the struggle that changes the individual, not the event.

This is a concept similar to resilience, but distinct from it. Two psychologist coined this term - Richard Tedeschi and Lawrence Calhoun. Post-traumatic growth is positive change that occurs in the aftermath of struggling with any major life crisis or traumatic event. Each person is different for each person. Post-traumatic growth is a process, not an outcome, and typically involves developing positive responses in these areas: appreciation of life, enhanced relationships with others, new possibilities in life, newly identified personal strength, and spiritual or existential change.

Dr Calhoun's book is Posttrumatic Growth Theory, Research, and Application.
