Why do automobiles have brakes?
To stop, right?
To stop. That's one answer.
Is there another answer? I heard this on the radio recently, and I jotted it down in my mental notebook.
Cars have brakes so they can go fast.
It's the ability to stop quickly that allows us to travel at speeds much faster than if we didn't have brakes.
Without brakes, we'd all drive very, very slowly. Brakes give us flexibility in stopping when you want, where you want, and how you want.
Analogously, in your life it's the very presence of boundaries that create new freedoms. Freedom isn't free. (Similarly paradoxical, having choice isn't what helps us in decision-making.) Having a gas pedal isn't what enables you to go fast. It's having a gas pedal AND a brake pedal.
Sometimes the short-term sacrifices in our lives are actually enabling us to achieve long-term goals. Your brakes are helping you go faster, even if it's frustrating to stop at the stop sign.
Also to note: how you answered this question clues you into how your brain operates when thinking about actions, functions, and relationships among systems. Thinking that brakes brake; and that's all, is a limited view on the capability of a function in a system. Often, each action or movement has multiple effects in the system.
How can you train your brain to look again and see if you can find other answers? It's very Jerry Weinberg (author of An Introduction to General Systems Thinking.)
The next time you do something, ask yourself how it works. And ask yourself, is that the only thing happening here?
So, why do cars have brakes?
