Mappers: What do you dislike about mapping?

[o_burnt_gravy]

I happen to be 3D skybox retarded it seems, because I followed half a dozen tutorials (on a non-complete map just trying it out) and it always either didn't generate in the right spot even though it was where it should be and I followed all the instructions. Also textures, the ones that are in there just don't seem to mesh with what I imagine in my head.
