When you reshape something, you change or transform it completely. You can reshape a lump of clay, but you can also reshape your plans for your life.
A government can reshape the country's energy plan, incorporating more environmentally friendly systems. And a school committee can reshape the high school curriculum, adding higher-level science classes and more choices in the art department. It's also possible to reshape things in a more literal way, squeezing bread dough as you reshape it to fit a different pan, for example.
