I get where you're coming from, and I agree to some extent, but I do think our tendency to weight criticism more favorably than praise (as if praise is "chaff" and criticism is automatically valuable) can be dangerous. This negativity bias unfortunately led me to adopt less-than-optimal ways of working in my younger years, because I assumed the people offering me criticism knew what they were talking about, when this wasn't always the case.

So while criticism can be valuable, I think it's worth reflecting an equally critical eye back at the person who is offering it, as upon closer inspection they may not be worth listening to at all.
