The word for the latter is egotism. We are taught to recoil from this in horror. If we see people exhibiting this trait (unless it’s countered by major smooth-talking likability), we mutter under our breath, “Boy that person really is full of himself, isn’t he?” and tend to disdain him. As for ourselves, we are not used to thinking of self as being particularly special. No wonder we have a hard time convincing an employer of our worth– we aren’t trained to see it ourselves!
So how do you keep that balance and still get a job?
First, start an exhaustive list of all the skills you’ve accumulated, in your previous jobs, in school, volunteering, anywhere. Ask friends, colleagues and family for help on this. This will help you see that you have worth. But at the same time, as you’re paying more attention to your increasing self-worth, pay attention to the worth and strengths of others around you. Heighten your view of them as being part of a world full of wonderful people, yourself among them.
