We find comfort in the way things are. We take the beaten path, and say, “if it ain’t broke, don’t fix it.” We think, it’s the obvious choice, as it was traveled by all those who came before us. 

In the book Think Like a Rocket Scientist, Ozan Varol gives the following example about how far this idea can go: 

The width of the engines that powered the space shuttle — one of the most complex machines humankind has ever created — was determined over two thousand years ago by a Roman road engineer… The engines were 4 feet, 8.5 inches wide because that was the width of the rail line that would carry them from Utah to Florida. The width of that rail line, in turn, was based on the width of tramlines in England. The width of the tramlines, in turn, was based on the width of the roads built by the Romans: 4 feet, 8.5 inches. 

What we’ve done in the past, has the power to shape what we do next. This not only goes for feats of engineering, but our lives as well. The decisions we’ve made throughout our lives create the waves that impact our future. So, if we do not like what our past has presented us, then we must change our behaviors, thoughts, ideas, mindsets, and lifestyles to create the change we seek.
