Self kudo.....It's actually up to personal preference. For me it just gives you a false sense of achievement, which is kind of....weird to do. Why would you lie to yourself? If people don't like your creation, then you can take it as a lesson and do it better next time. In my opinion, self-given kudos are just a bad way to deal with people not liking your stuff.
Again, this is my personal view and I don't know about other people.
