Rough= having an uneven or irregular surface; not smooth or level.
Life is like a rough ride on a rough road! Sometimes life experience seem like you are taking a ride in the car and all of a sudden there are signs that say "Rough Road Ahead"! Think about it, there may be potholes and rugged terrain. Do you turn around or do you take your time and proceed ahead? I know the road may be rough sometimes but keep going. Just drive slow and proceed with caution! The rough road only last for a couple of miles! Eventually the road will change from rough to smooth again! You will see a sign up ahead that will say "End Road Work! So, no matter how rough the road of life is keep going! It will END!
