Many people are genuinely not "smart" enough. Saying they are, is likely to cause suffering and waste resources, on both personal and societal levels. It's also insulting towards the intellectually disabled.

"I'm not smart enough" is not always a cop-out, or "a (lame) excuse". It can be a sign of maturity, and a cause of significant respite. Knowing your limits allows those who are intellectually limited to pursue tasks suitable to them, and still be satisfied with life (even though they haven't created Facebook or Pinterest).

Even for the more gifted of us, knowing your limits might lead to a happier life..

Exactly people are different, some are smarter than others. Otherwise everybody would be an engineer or medical doctor or some other high status high paying job.

This whole mentality that everybody are born equal in mental capacity is a likely cause of stress and depression among many people today.

People are born tall, small, fat, skinny, smart, supid. Just find your level and optimize your own happiness.
