The article hits on something that I believe everyone is at least aware of. Id argue the next generation is best suited for not having this issue that the current generation does have as they at least seem to think about everything and are very careful about tying their identity to work which prior generations seem to do without much thought (for better or worse).

I'm in my 50s. About two months into retirement I fell into the deepest depression of my life because I couldn't shake the "who am I without my job?" question. It took almost a year (and therapy) to accept that I still add value without working.
