Friday for real,and trying to blog for real....

I'm having some difficulties getting the hang of blogspot. I wanted to post into categories, but didn't know how. Nor do I know how to do it now. I tried , but alas, my categories do not exist. So, my blog is currently mishmoshed all over the place, no division, intermingling all over. ARGH! I will get the hang of it, and eventually put all my stuff into the right place. Maybe....
I am totally open to suggestions on how to do things on here, in simplest terms possible, because i just don't have the time to read the instructions in the first place.
