Throughout the day，your energy rises and falls．At your peak，you're likely to perform 30 to 40 percent faster and more accurately than at your low，says Lynne Lamberg．Synchronize your schedule to use your natural energy supply efficiently．
Alertness is the highest and concentration most focused between 9a．m．and early afternoon—a good time to crunch numbers or writea report．Dive into the hardest tasks first．
Extend your high-energy morning with a late lunch．Many people are still going strong until one or two o'clock．Why break the momentum？

The dark side of your cycle is equallyim- portant．For daylong energy you need a good night's sleep．On average，Americans get about seven-and-one-half hours，although some need more and others get by on less．You're getting enough sleep if you wake up without the help of an alarm clock and don't feel the urge to nap during the day．
