One of the most efficient everyday optimizations I've made in the past few years was to adopt the lisp-style naming convention for my local file system hierarchy. Removing all capitalization and special characters (other than the dash) makes navigating via CLI much easier. And having a predictable naming scheme means I rely on tab completion slightly less too, as I have more predictive capability regarding how I might have named things in the past. More generally, treating my home folder as, essentially, an exposed API for which I'm the primary consumer has paid dividends.
