The impostor syndrome: How to deal with lack of self-confidence in academia?

Life in academia can be very fulfilling: On the path from being a master student to a senior professor, we achieve mastery, we have a lot of autonomy in our work, and we have the nice purpose of improving human knowledge. However, we are often struggling. Because life in academia is very competitive and sometimes isolating, a difficulty that a lot of us face is the lack of confidence in our own capabilities, work, and achievements. This can lead, for example, to procrastination, to the fear of asking questions, or of applying to a high-level position... I hope this talk will be the occasion to discuss hints on how we can manage to turn these difficulties you or your colleagues face, into advantages.
