If you feel stressed by responsibilities at work, you should take a step back and identify (识别) those of   61  (great)and less importance. Then, handle the most important tasks first so you’ll feel a real sense of   62  (achieve). Leaving the less important things until tomorrow   63  (be) often acceptable.

Recent   66  (study) show that we are far more productive at work if we take short breaks   67  (regular). Give your body and brain a rest by stepping outside for   68   while, exercising, or dong something you enjoy.

If you find something you love doing outside of the office, you’ll be less likely   69  (bring) your work home. It could be anything-gardening, cooking, music, sports—but whatever it is,   70  (make) sure it’s a relief from daily stress rather than another thing to worry about.
