In a discussion about choices about occupation, I shared the image of this tweet. The following was one of the replies:
Of course you can sit and complain about it, but it tells you about your own shortcomings be it laziness, cowardice, fears of all kinds lack of initiative etc.
Further the commenter pointed out that
Personal success or happiness after (everything else being equal) is determined by your personality.
He claims this using the theory of delayed gratification. His point being [from the wiki link]:
In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI), and other life measures.
Actually he might be right. I have no idea of modern cognitive science results. So I want to know the following:
Are there results in cognitive sciences that show personal success or happiness is determined by one's personality? And that any occupation failure is determined mostly by personal shortcomings and is largely independent of social identities?
