There are people (me, for example) for whom their work is an important part of their identity. For these people, every rejection of their resume hurts because it's like someone is rejecting them personally.
I want all these people to remember that this is so far from the truth: your resume is just a small fraction of your work journey, and it's being read among hundreds of other resumes, and may not even be read by a human - and you are so much more. Keep going!
