I think you see what the issue is, and I agree with you. In fact, I've experienced the exact same thing as the person in the article, about 20 years ago. From here you could gather how old I may be.
I've been so down in depression and anxiety, and I could easily have penned the article myself during my downtimes. Without giving way too many details, my desired state back then was the home with a white picket fence, a couple children and a lovely spouse.
The output (reality) was that I was became divorced, my only child kept away from me, and living in my parents basement as a fully grown adult, going through nasty nasty court battles. I lost all my money to lawyer fees.
The Comparator between the output and the desired state was HUGE.
Then this affected my job performance, causing all sorts of other issues. I hit rock bottom, and then I made a decision: crawl under a rock and die, or pick myself up. I chose the latter.
Looking at the positives of what I did have (my life, able to walk, commute to work, give money to charity to help others) etc - this is what made me turn my life around.
Lots and lots of hard work ensued, and some missteps along the way (some health issues due to stress). I cleaned up my diet, sought professional counseling help, went to the gym, personal trainer, took medication, did better at my job, got a promotion, found a new spouse, bought a house again.
My desired state mentality has also changed over the years. Instead of trying to get the latest gadget, the biggest house, more promotions, more everything - I am now content with what I do have. I am content with the reality I have created.
We all have a life story, and different perspectives.
