I have noticed a trend: when I am developing and I find a solution to a difficult problem it is normally because in some way I have regained sight of the bigger picture. For example, I might see any easy way to sidestep the issue all together or I might gain an understanding of how seemingly disparate objects influence each other. To make matters worse, the more difficult a problem gets, the narrower and more intense my focus seems to come which blinds me even more to the bigger picture.

Does anyone experience this? Does anyone have a solution that works for them? Is "sightedness" just an attribute of inherent intelligence that I have no real control over?
