Hi Cate,
As far as the web site, I did a right-click and "inspect", and it showed a "500" code, which means server error. That's pretty vague, though, could be anything.
I think ruminating on the past is a tough habit to break. I mean, there are good memories, too, but for some reason the mistakes come back to haunt you more than the happy memories, at least for me. I think I heard Tom Brady, the quarterback for the Patriots, who has won 5 Super bowls, say the losses sting way more than the wins make you happy, something like that. So, if a guy that successful feels it, imagine how ordinary humans must.
That said, it's obviously one of the most important things to be able to do, to move on, stay in the present. There's a self-help guru named Ekhart Tolle, you may have heard of him, his big thing is never to think about the past, that the ego, the sense of self, is a false construct based on flawed, transitory thoughts. Dale Carnegie says live life in "Day tight compartments". I know Zen is all about staying in the present, so it's not like this idea is anything new. I've never succeeded in that so far, but it's on my list. Pretty far down, though, I'm chasing the lower-hanging fruit first.
