Thank you for this comment. I suffer severely from low self esteem and impostor syndrome. Coworkers from several previous jobs have even gone so far as to tell me they thought I was a genius, and it made me feel immensely guilty every time.
I'm going to try putting some of your suggestions into practice. I'm at a crossroads in my career, having recently been separated from my job due to budget cuts. Even though my job loss wasn't an indictment of my worth as a person or the craftsmanship of my work, my confidence still took a significant blow.
Staying motivated while looking, applying, and interviewing for jobs you believe you don't deserve to get is challenging, to say the least.
