No roads are perfectly even, there will always be sharp curves or rocky bumps along the way. Even the seas have calmness during some voyage but surely has stormy days too.
But is the condition of your journey the one to dictate your travel? Not really.
When we ride an airplane we trust the pilot. When we board a ship we trust the captain. Therefore it is the one who holds the steering wheel that matters if he or she can whether the bumps along the way.
We are the captain and pilot of our own vehicle it is us who matter the most in this journey.
