Yeah, no, don't get me wrong. I think it was a fine post. A necessary one, at that. I've seen quite a few people who fall under your category of posts you would immediately stop reading, that's why I mentioned that. I do agree that being discouraged because of criticism is a sign that some people wouldn't be able to make it.
Different strokes for different folks, I guess. Speaking as someone who hasn't made it, I definitely appreciate the reminder to do better and improve. But, I guess I just lean more on making feel people encouraged and included. I guess that's why my work isn't as widely read :D
