Does the IQ define certain characteristics of the character or does the character shape the IQ? example: a high IQ individual will be able to solve problems faster than his peers will that give him more confidence? or because he is a confident individual his IQ will help him to search for bigger problems to solve?

What about IQ and porpoise? does high IQ individuals have meaning and porpoise because they are able to see how their actions affect their environment?, this seems to be present in the people who is able to see a career path and not only a job, do high IQ people "see themselves in a professional career" and low IQ only see a "job" because they are unable to attain a career?
