I just found out about your writing journal yesterday, so also just started reading. I wonder why you don't post your writings in the communities?

"[...] I worry I won't have anything interesting or insightful to say [...]. What could I possibly add?"

I think the reader's reaction to specific lines is interesting enough. I always wonder what other readers think about lines that were important for me, if the words brought up similar imaginations/emotions/thoughts. I think whatever you feel like saying is worth speaking it out, especially for the author.
