I did feel that way when I started writing on the site over a year ago. And I could see how people might feel that way when they're first starting out, You're really putting yourself out there because you only have a sub or two, or a like or two. (though, now, you can't see who liked an episode which is sad. I miss seeing those names. It's less personal now)
but, after finishing a couple of books and interacting with subscribers, it gives you such a different outlook. Like you, I sub my own work.
I also like my own work. as stated somewhere above in the comments, it's a way for me to gain more confidence in myself and what I write, though apparently, that makes me conceited. (not throwing shade at anyone over it. guess it is what it is.)
