Let us share about blogging mistakes

Everyone knows that success does not come easy. It means a lot of learning, and making mistakes, and correcting the mistakes.
Since i started blogging 8 months ago, my mistakes in blogging are enough to compete with the thickness of Oxford dictionary.
First, I dont know about seo, keyword density or whatever.
Second, I dont know about backlinking
third, I dont know that new blog needs almost daily update
fourth, i dont that how to add "no-follow" tag to affiliate links.
What about you? How many blogging mistakes have you made and how do you rectify the mistakes?

Learn from the mistake.. that is the most valued experience. ;)

my blog is about seo, and there are many seo articles in my blog. you can visit. my blog URL is besteast.blog.com. :):p

Just read, read, and read and you will slowly pick up things to make your blog successful. And never give up. Good Luck.
