Remember this

I am Lady Wisdom, and I live next to Sanity.

And I also am working on the three Bs. They may not end up being Bs, however.

The three Bs

The three Bs are the three types of things you should try to avoid reading or writing at all costs. They are:

1. Banal
2. Blasphemous
3. Belligerent
   

Banal is the opposite of interesting. It is boring to the extreme, pointless, and un-informative. Definitely not worth your while.
Blasphemous is the opposite of informative. It requires more explanation as I've twisted the meaning somewhat. What I mean is not caring what the facts really are, and simply heckling people with insults and accusations of lying. Doing anything to win the arguement generally falls under this
The last one is Belligerent, the opposite of inspirationa. This category is the deliberately annoying, insidous, parasitical stuff, which is actually extremely rare. Most things you would think are Belligerent are actually Banal or Blasphemous. It is the intent that makes this category the worst.
Of course, it doesn't really matter whether something is Banal, Blasphemous or Belligerent; as soon as you identify it as one of these, run. Or rather, stop reading. Actually, stop writing it if that's the case.

The three Is

Everything you read or write should fall under one of the Is:

1. Interesting
2. Informative
3. Inspirational
   

The most basic requirement is that it is entertaining, amusing, or otherwise interesting. Even if there's nothing else useful about it, it can still be worth a read if it's interesting.
The second possibility is that it's informative. Information is always useful. Unless it's disgusting. In which case it shoud be avoided.
Finally, it should be inspirational. There is so little in this world now that is great, anything that rebels against that should be praised.
