Indeed life is like a long unwinding road heading somewhere upcountry; those are always several kilometers long and never really seem to come to an end. 
Some parts are straight while some have bends. Some are uphill and some go downhill. Some parts have bumps while others have potholes; potholes of varied depths and sizes.
But they all make part of YOUR road.
Question is, do you know your destination?
Are you on the right road? 
As long as you are on the right road, all the challenges (potholes, bends, sharp corners, bumps, etc) that come while you are on that road don’t really matter. They are there for a purpose. They are there to prepare you for your destination (destiny).
And even if you are on the wrong road, you can still decide to find your way to the right road, as long as you know where you want to go in the first place.
All the same, enjoy the road you are on currently, complete with all its bends and turns, bumps and potholes. 
And if you find yourself in unfamiliar territory remember this:
"Throughout the centuries there were men who took first steps, down new roads, armed with nothing but their own vision" ~ Ayn Rand
