How do you feel about non-constructive criticism? Do you get upset or try to ignore it?

Unconstructive criticism is a challenge for professional and personal growth. I try not to get upset, but to detach and analyze whether there is at least a grain of useful information in it. If the criticism is simply negative without specifics, I don't take it to heart to avoid wasting energy. It's important to stay calm and focus on improvement rather than emotions.
