What to write?

So as I sit in front of my laptop staring at a blank screen wondering what I could write that would interest my followers.  I took the advice of a classmate and clicked the "Next Blog" button.  I clicked through about 4 or 5 and nothing seemed to peek my interest, but then I seemed to notice a pattern: how do all these authors make their pages so snazzy?  I followed the blogger design and did not see any of these cool backgrounds and graphics.  One even had music!  I want to to learn ways to pretty up my blog.  Perhaps if I could personalize it to fit me better I would be more incline to write in it more?? :)
