Mmm. Yes, I can certainly imagine that if you know a particular cluster of difficult situations is approaching and roughly when it'll arrive, that's a particularly good opportunity to have prepared your responses in advance and psyched yourself up to exercise self-trust.

When I wrote the post above I was mostly thinking in terms of things that come on you unexpectedly, because that's more the sort of thing that tends to happen to me. I'm inclined to think that having to exercise self-trust unexpectedly is qualitatively more difficult, other things being equal – but on the other hand I'd bet that the 'bad things' you're hinting at there are significantly worse than the ones I usually have to worry about :-)
