I have no idea what I am doing

The title of my blog is aptly "I don't know what I'm doing" Which is evident by what I write now and what I have written before. Why does anyone write a blog when most of the time what is written by the blogger is of only interest to the writer and no no one else. I am surprised that there are people with nothing better to do who will look at someone's blog, read it and remark how insightful it was. Some where out some one may read this and declare how insightful these words are, in a single word I respond; Bovine.
