If a "modern" high level language is like a shop with machines full of safety features and refinements, lower-level languages are similar but the bandsaw won't try to stop before cutting your fingers off, and assembly is like building by hand (some platforms might give you an electric drill and 50 different saws, others, just a chisel). In many ways, it's easier to think about, but it also lacks the easy guide-rails and labor-saving machinery that make high level attractive. Assembly will give you the context to really appreciate why higher-level languages work how they do, especially the older ones like C.
