I love this:
No one wakes up one day and decides to create good quality posts
So true! Lots of thought and editing goes into any good quality post. It's rare that you get all of your thoughts and ideas down in the first try without having to make at least a few edits :)
Even as you write you change things. I did that in this post and something that I wrote first ended up being at the bottom of my post as I added more.
