The achievements of others can have two very different effects on a person. There is something about seeing a rival succeed that can make you go one of two ways: either it will cause you to doubt yourself and question your capability or it will make you drive forward and disregard the victories of others as inconsequential.
It’s important to keep an eye on the competition, but you can never stress out over what they have accomplished. What happened, happened. And the sooner you get back to work after a loss the quicker you get to a win. The most skilled and cool-headed businessmen will use that sting of defeat to push them and their team to achievement the next time around.
