Assistance with Blogging

I have a bunch of topics and I want to narrow them down and categorize them so all can fit on three blogs. I racked my brain for the past three years for putting this stuff together. to try to accomplish this I created and dismantled over 140 wordpress blogs and even about three Drupal bogs to find how to put this together. Can someone or someone(s) organize these for me? I've tried for 3 years, don't take it lightly, YEARS!:

Please, please pretty please arrange these items above to fit into three categories. I've tried. Start with easy choices and if the remaining ones are difficult to put into a category, put them in a list by itself or squeeze them into one of the first three lists. I prayed to God about this and he sent me here.

 

What drugs are you smoking? It's always religious people who are nutjobs.

 

Why just three categories?
