On tools: "Tools" are sometimes useful for getting a job done. - "Good" tools don't get in the way of getting a job done, and often make tasks easier or faster to perform. - "Great" tools can enable entirely new ways of completing tasks, and sometimes enable completely new types of things to be accomplished. On amateurs vs pros and mastery: - Amateurs worry about figuring out how to get something done "right," (i.e. typically with one instance in mind) and often blame their tools for poor results. - Pros worry about figuring out how to manage the outcomes of jobs/tasks/etc to make sure they don't go "wrong." (e.g. considerations of failure modes, maintenance/upkeep/sustainment/etc..)
