Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.

Having a Congress with a more diverse educational and professional background would serve the country well. And given the budget challenges facing America today, we might benefit from a few more cold, calculating problem solvers, and fewer courtroom impresarios.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
