If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point.

If one wants to work more efficiently at his low point in the morning, he should _______.

A.change his energy cycle

B.overcome his laziness

C.get up earlier than usual
