This gets a little tricky though, because other people's reactions aren't always a good metric. If multiple people are telling you something, then it's almost certainly pretty pertinent to listen. If only one person is telling you something, it's probably worthwhile to reflect on that in most cases, but you may also want more feedback before you go too deep down that rabbit hole. But this all depends on the people you're around, what kind of criticism/feedback you're receiving, and what's behind the other person's intent for telling you.

Sometimes we end up in relationships that involve gaslighting and emotional abuse, and it's not always obvious to us. Sometimes, we don't have a strong sense of self and we look outside of ourselves for validation more often than not. Sometimes we interact with people whose internal experience is wildly different from our own.

IMO, it's important to work on strengthening our egos when they are fragile, and to form our own foundational sense of self from which we can build atop with feedback from others.
