What is the major difficulty all map makers have?

The major difficulty all map makers face is accurately representing three-dimensional terrain and spatial relationships on a two-dimensional surface. This involves making choices about scale, projection, and detail, which can distort certain features while preserving others. Additionally, balancing aesthetic appeal with functional clarity poses a challenge, as maps must be both visually engaging and easy to understand. Finally, staying current with changes in geography and infrastructure adds complexity to the mapping process.
