I would be TERRIFIED if psychological checkups became routine, and see that as near-dystopian as some aspects of brave new world. For so many people (I say this now being married to a psychologist of my own) including myself are diagnosed with disorders of extremely variable diagnostic validity at extremely young ages (beyond even what the DSM, with its already spotty contents, would recommend) and then medicated past functionality and/or told we have something wrong with us.
What would have helped me? If instead of being told "you need these pills to fix you" someone told me that "normal is a spectrum", and people even with behaviors we love to tag with fancy names and try and treat can learn to control them and live perfectly normal lives without drastic intervention.
Don't take this as a "we should ignore psychological disorders", it's not the intent at all. Take it as a, I've seen the culture that arises out of LOOKING for mental issues rather than encouraging growth and maturation, and I'd rather resort to a psychological approach as we do with antibiotics, _when needed and after extensive exploration of other options_, lest we unconsciously do ourselves further disservice. Although I have a different takeaway than you though, I'd echo the same guiding thought, "don't assume he or she is lazy or doesn't want to succeed" but would append "or assume they are broken."
