Writers have BIG egos.
Even more than that, writers need big egos. Without a bit of ego, a writer is someone looking at a blank page, thinking, Why would anyone read something I wrote. I wonder what’s on TV.
However, these big egos can make it difficult for writers to work with other writers, to allow others to critique their work, to not feel like they’re in a competition. Sadly, this kind of negative ego will only turn back on those who put it out. I’ve seen promising writers learn bad habits as they refused to listen to good advice, “knowing” that they were the better writer.
Don’t let it happen to you.
It’s important to weigh the advice of others and not take it as gospel, but it is also important to listen to other people, to allow yourself to be taught. Sometimes, all it means is keeping your mouth shut and taking time to think about something.
