“If it isn’t broke, don’t fix it.”
A saying that has been passed down forever, at least so it seems. But it’s solid advice. If it works, it works. Why try and change it?
Does the argument hold water though?
Yes, the mousetrap worked. But people still wanted to build a better one. The horse and buggy was a great method of getting around. Till someone invented the automobile. You could do calculations by hand, but why not use a calculator?
Just because something isn’t broken doesn’t mean that an improvement in its functioning couldn’t make the world a better place.
