I guess the best way, in the ideal world, is to stop trying to pin blame altogether. Easier said than done, though.

I saw a really good Tao quote about this. I don't recall exactly how it goes, but it's something like:

"If you blame others, then there is no end to the blame."

It would make sense to extend that to ourselves, as well. Blame is, in my opinion, getting stuck in dwelling on the past. If we stick to the present (what can we do NOW to fix the problem) and future (working toward how we want things to be), then blame shouldn't enter into the equation much, except as a lesson learned.

Onward and upward!
