Yes, I've never understood it. Not to be insensitive, but, life is hard. If you want to be an adult, you have to face some hard things. If you want to challenge yourself intellectually, at uni for example, you will have to face some hard truths, shocking history, terrible actions, but that is how you grow. Strength and resilience comes from facing these challenges and coming out the other side a good person, knowing that life is tough and unfair, but not letting that weigh you down.
