I totally get this view. I have kids too. But the older I get, the more I know there is a whole lot of value in young adults learning how to adjust to lost opportunities, facing what feels unfair, and figuring out how to handle situations that are not equitable.
They will need these skills and you don’t just have them out of thin air. Life is a whole lot more enjoyable when you have the skills to deal with adversity and you stop wasting time and energy feeling personally wronged by lost opportunities, things that seem unfair, and unequal outcomes.
