I think a lot of serious deer hunters fall to strategy "panic" from time to time. They formulate a new or modified hunting strategy in their head long before season starts, but if that new strategy doesn't pay off fairly quickly once season starts, they begin second-guessing that new strategy and sort of "strategically panic." Once that happens they dump their new idea and fall back on the comfort of their old, and often unproductive, strategies. I often found that if a new idea hadn't panned out by mid-season, I would strategically panic and just go back to all my favorite old stands without any logical reason or strategic plan involved. Rarely does that work out well.
Perhaps the new idea was a failure, but often we really don't give the new idea a thorough evaluation. As the drive to be successful ratchets up self-imposed pressure, we tend to abandon new ideas far too quickly.
I believe at least a full season is required to evaluate a new idea (and really, several seasons). In an attempt to force myself to give a new idea a full evaluation, I've gone to formalizing the plan in writing, as well as all of the reasoning behind the plan. I then force myself to read through the plan regularly throughout the season to keep my (hopefully) sound reasoning fresh in my mind. If I don't have it written down, my mind will immediately start second-guessing the original ideas, selectively forgetting the reasoning behind the ideas, and making excuses as to why I should abandon the plan.
