Master the basic, existing tools for their job. Maybe that's shell scripting, git, screen/tmux, ssh (keys, port forwarding, etc), microsoft excel, etc. A shocking number of people use things day in day out for years, but basically never move beyond a beginner level of proficiency, and it takes them minutes to accomplish basic tasks that should be done in seconds.
