The dog longingly looked at a bone on the other side of the fence. He drooled and looked and looked and drooled. In fact, he became so fixated with the bone that he wasted away to scrawny shadow of his former self. At that point he could squeeze under the bottom rung on the fence to reach the bone. He gobbled it all up, and became so fat that he couldn't return to his own side of the fence.
Some thoughts consist of one-way stepping stones.
The dog hungrily approached the bone on the other side of the fence. Identify the trade-offs and the traps, the compromises and the alternatives. Obvious targets may be not the ultimate goal. Once upon a time a hungry dog spied a bone behind a fence. Try as he might, he could not get past it.
