I think that sometimes what happens to people is that they build the life that they implicitly believe they are “supposed” to be living because that is what they see everyone else around them doing, rather than based on an honest self-assessment of whether this really is the what will make them happy. When they realize that this life is not actually making them very unhappy, they look for outside factors to blame because they did everything that they were “supposed” to be doing so it could not have been their own misinformed choices that led them to this point.

And in fairness, no one chooses where they are born and the cultural conditioning that we receive, so this is not entirely their fault. It is really a societal problem that we do not encourage enough people to engage in true self-introspection to figure out for themselves what is important to them and what they want to get out of life so that they make these kinds of decisions with great deliberation and personal self-insight rather than taking the default option.
