Okay...use it or lose it...I can't get the blog to do what I want

It must have a mind of its own.

I am not sure if this blog is supposed to stand alone and I start a new one every time or if paddysprogress is the blog and I add to it what I want to say from day to day...And the picture, how do I change the picture on this blog?

I am slowly going crazy and finding it difficult to use this and I must now stop so that I can go and have a decent nervous breakdown and resume this later.
