Well, I don't know. I may not be winning any Nobel prizes anytime soon and even though, I always look forward to the positive comments from people, praising my writing or creativity, I also look forward to my own reactions. When I create an amazing story and I just smile happily to myself because I know it's beautiful. And even though some of my content maybe better than the others, I'd never see it as drab content.
I'm usually careful as to what I put out there but make no mistake, what I write here is usually all me. No matter how people view me as afterwards.
With that said, I think you're a good judge of character so if you say that user isn't writing drab content in the least, he or she had better be made to understand that so they stop undermining themselves.
I'm not sure if they were intentionally undermining themselves so much as reacting to other things in their life that leaves them feeling a little unhappy about themself. It's common for people to do this and most have probably done it at some stage or other.
I'm not sure that person will see this post, but what they said prompted some thoughts about content and how the author and others see it, hence this post.
You said your content is beautiful and that's your opinion which you're entitled to, others may feel the same about your content also. I think mine is average, like the rest of me, although I still get enjoyment, a sense of achievement, and some personal value from the process of creating it. That's where the reward begins, and if I'm to get a favourable comment here and there that's just a little extra on top.
Thanks for your comment and all the best with your writing.
