Why do we have brakes in the cars?

Once in a physics class, the teacher asked the students:
"Why do we have brakes in the car?"
Varied answers were received:
To stop
To reduce speed
To avoid collision etc.

But the best answer was:
To enable you to drive faster

Give it a thought:
For a moment, assume you have no brakes in your car, then how fast will you drive your car?
It’s because of the brakes that we dare to accelerate and attempt to drive faster to reach destinations. 
At various points in life - we find our parents, teachers, mentors, & friends questioning our progress - our direction or decision. 
We consider them as irritants or consider such inquiries as 'brakes' to our ongoing work. 
But, remember, it’s because of such questions (periodical brakes) that you have managed to reach where you are today. 
Without these brakes, you could have skid, lost the direction, or met with an unfortunate accident.
I am deeply and sincerely grateful to all my priceless BRAKES.
Appreciate the 'brakes' in your life.
Without them, we wouldn't be 'where' we are today.
