Clearly it's not impossible to do nothing. This guy is proof. But there are those who actually do the impossible.
In 1895, heavier than air flight was impossible; then the Wright Brothers showed up on a beach at Kitty Hawk. A sub- 4 minute mile was impossible until Roger Bannister proved otherwise in 1954. In 1926, Philo Farnsworth's television invention was dismissed as financially impossible and a waste of time. Edison's electric light bulb was described as a conspicuous failure, critics claimed the horseless carriage would never come into common use, and in 1949 it was claimed that we had reached the limits of what was possible to achieve with computer technology.
In the words of Nelson Mandela, "It always seems impossible until it's done."
