Google is quoting Abraham Maslow, "If you only have a hammer, you tend to see every problem as a nail." If you only have a pneumatic hammer, then you tend to be alert for big problems, and you aren't be put off by them. Of course, if you only have a computer-controlled high-precision 3-dimensional milling machine, you might see a lot of problems as potential opportunities.
My main tools are all in operations research. The training has taught me to look at the possibilities, and how the world could be, and then find the best route there.
