This sounds like really dramatic title, doesn’t it?
It’s not as bad as it might sound, but at the same time something that many (me included) suffers from. The curse of never thinking that you’re good enough or rather.. Always having the nagging sensation of everyone and their toddlers can do whatever you can and then more, soon they will figure it out!

This is because of a twist where somewhere deep down a person might hide feelings of superiority or at least expect this of themselves but on a more shallow level of personality live with a
Second, looking at a number of measures of the self, we found selfuncertainty and inauthenticity among those scoring higher in vulnerable narcissism, including higher levels of impostor syndrome, weak sense of self, self-alienation, accepting external influence, and low self-esteem. All of these factors limit a person’s quality of life, and indeed vulnerable narcissism was negatively associated with every measure of well-being we administered, including measures of life satisfaction, authentic living, autonomy, environmental mastery, personal growth, positive relations, purpose, and self-acceptance. 
But as I already mentioned, this is something many if not every normally functioning human being “suffers” from. Some would say that it’s because of our society or what not. Humans are complex, let’s leave it there.
