Does havg a dream career conquer social anxeity disorder?

Not so simple: It is never that simple. People with great careers and great jobs can still have serious social anxiety symptoms. Having these symptoms can frequently prevent people from interacting with others and therefore they miss the opportunity to have their "dream career".

While having a dream: career can certainly help with work life satisfaction, it does not necessarily mean that symptoms of social anxiety will disappear. Speaking with a therapist could help with social anxiety.
