I’ve got serious imposter syndrome and am very bad at selling myself due to a long-standing lack of confidence. As a result I’m always on the back foot at work (doesn’t help that I’m part-time since having a child) and am consistently overlooked for opportunities. I have more experience and qualifications than most I work with but I just can’t seem to back myself. Always feel I’m going to get called out for being stupid or incompetent. Those around me seem to exude confidence and belief in themselves. I have to do something about it but no idea how to convince myself I should be confident about my ability. I often wonder if faking it until you make it works. Any thoughts?
