It also depends on how that criticism is made and what criticism it concerns. In general, not all criticism is justified. I am increasingly able to see it as a learning opportunity and not (immediately) get defensive.
Today I got feedback and didn't ignore it. I immediately went to do something about it. So I changed my previous answer, because I can say I'm ignoring it, but in practice, I'll take it closely and use it to improve. Learned something about myself today.
