The world we live in is becoming increasingly complex and uncertain．And with it，the conventional thinking of yesterday is no longer sufficient．Creating real breakthrough opportunities requires a fundamental change in our thinking．As Einstein said， "We can't solve problems by using the same kind of thinking we used when we created them．"
   There's no better example of this than the myth of the four-minute mile．
   For centuries，runners had been attempting to run a mile in under four minutes．In the 1950s，the attempt to break the barrier took on renewed importance，and a number of famous runners publicly and unsuccessfully attempted the challenge．Many of the newspapers of the day began to question whether humans would ever be able to run a sub-four-minute mile．Then，in 1954，a man named Roger Bannister did the unthinkable．He broke through the imaginary barrier，running the mile in 3 minutes and 59.4 seconds．It was an amazing achievement．
   But here's what's really interesting：it was only forty-six days later that another runner broke Bannister's record．And the following year，two new runners broke the four-minute mark in the same race．Dozens followed，and as of this writing，more than 1，400 runners have accomplished the goal，including one runner who ran two miles in less than eight minutes．
   Did something change with respect to human body，track conditions，weather patterns，running shoes，or the human diet between the start of Bannister's race and the few years that followed？No．So what explains the sudden and dramatic explosion of athletic achievement？
   The myth's unimaginable power over runners had lifted．What Bunnister had done was not just break the four - minute - mile barrier；he shattered（粉碎）the myth that created
the barrier in the first place．This paradigm （榜樣）had offered a set of actions available for runners to take．Runners were really free to run through the invented boundary．
   Creating breakthroughs requires shattering the myths that limit our imagination and lock us into conventional thinking．Think about your own situation．What myths are you stuck in？And what would be possible if you had the courage to challenge the myths？
