18．As the new semester begins，millions of college students across the country are trying hard to remember how best to write a paper or，more likely，how best to delay that paper．
Procrastination is the thief of time and a lot of students suffer from it．They can spend whole days in the library doing nothing but staring into space，eating snacks，surfing the Internet，watching videos and looking at other students sitting around them，who，most likely，are doing nothing either．
Paralyzed （使失去活力） by their habit to procrastinate，they write micro blogs about their fears，asking their online friends if they sometimes have the same issue．But this does nothing to break the spell （魔咒）．
According to a recent report，95percent of us procrastinate at some point and 20percent of the world's population are always procrastinating．The figures are disappointing．Procrastinators are less wealthy，less healthy and less happy than those who don't delay．Procrastinators like to find excuses to justify their behavior，but BBC columnist Rowan Pelling says they are all wrong．
Many procrastinators tell themselves they are perfectionists who work best under pressure．Pelling says this is nonsense，as work done at the last minute is more likely to have mistakes than work done on time．The behavior of procrastinators often makes them feel ashamed，inconveniences others and annoys loved ones．
Pelling also points out that procrastination feels particularly delinquent （过失的）in a society that thinks of speedy action as admirable，and，at times，even as a moral good．
Fortunately，social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it．Piers Steel，a Canadian social scientist and author of The Procrastination Equation，believes human is"designed"to procrastinate．Nevertheless，he suggests a couple of good ways to get through the task at hand．
