I've had that happen. I also appear to have managed to short-circut the cycle - it's been a few years since I've had it happen. The key, as far as I can tell, was to realize that it's literally impossible for someone to have all the answers - the world is far too complex for any human to understand that well.

Stage one and two are still about the same now, but the other three stages blend together - I automatically look for the flaws and limitations of a worldview or body of work at the same time as I try to find ways that it's useful, and I only incorporate the parts that seem worthwhile. I've also found that I'm more open to unpopular or 'obviously wrong' worldviews now, in the sense that I suspect that there's at least a bit of usefulness to be found in any of them.
