Sweet paws. Never heard that one before, sounds cute. I don't get stressed or sad, I get angry, aggressive, and push harder. It's actually a valuable tool if you can keep it under control.
I believe that miracles can happen, but they are statistically rare (which is why they're miracles), and failure is much more probable. My combination of "It's gonna be bad anyway" and pushing harder has brought me through quite some tough times. It also makes any little thing good it's own little miracle (if you expect bad, but good happens, it is quite a surprise), and almost completely negates bad results (if you're expecting bad anyway, you're ready for if it hits).
And I went off rambling again...
Oh, and I don't have the time to calm down and breath.
