Does it ever get easier?

Just had a performance review with my PI where she basically said I’m doing everything well but not really exceptionally enough/im not going above and beyond and it’s triggered an identity crisis (made worse by the NIH Hiring freeze) . I see her point, but what if I’m simply not exceptional and not capable of going above and beyond? Does it ever get easier to take that sort of criticism/not take it so personally/ have some emotional resilience? Is there anything I can do to expedite the process?
