Very sage advice from Chuckles.....
what is 10nm ahead and a few miles left and right are the important bits.
Commonly referred to as
The Big Picture!
That largish mountain with the radio mast on it up around 15 miles ahead, that body of water/resovoir off track to one side (what side of that should I be flying?), those grain silos to the left/right of that road junction, that large esturary mouth etc etc.... It is all in the practical application of the big picture, and believe it or not it can come down to the shapes of these features or a combination of where they are in relation to each other that can give you a good fix of where you are at. You can then fine tune it to a point where you can say with certainty "me here!"
Good onya, keep at it.
