Yada yada yada...

To tell you the truth, what I was going to say has already been said.

In fact, it's been said at least a thousand times!  (Hello, bloggers?
Isn't there anything else you could be doing right now?)

Hillel put it like this: "'What is hateful to you, do not do to another.' This
is the entire Torah;  all the rest is commentary.   Now go and study it."

Yeah, I think that pretty well sums it up.
