Where to begin a blog

I have fought off the blog spot for a couple of years now. I find it over-whelming to start something like this in the full swing of daily life. What does the first typed letter bisect? DOes it come after breakfast/before 11:00 or is it more an afternoon tea piece? Do I just dive right in with the latest thought or does the latest thought need a little backround for understanding. So this first blog entry is actually only a precursor to the blog, a final weak protest before plunging headlong into the online diary. Just saliva on the reed, rosin on the bow, a little hot water the throat. I will be back with my blog heart broken in.
