For those who are musically inclined -- When learning to play a musical instrument (including voice), the distinction between long work and hard work is the difference between spending time and making progress. Long work is mindless practice; hard work is identifying weaknesses and using targeted practice to improve. For those in marketing -- Long work is spending more on an advertising campaign; hard work is determining what increases the conversion rate. For those in computer science or mathematics -- Long work is implementing a brute force approach to calculating a specific result; hard work is generalizing the problem and generating a class of results. For students -- Long work is studying to pass a specific exam; hard work is internalizing the fundamental principles of a subject so you can derive answers regardless of the particular exam questions.
