Does smart work beats hard with? What are some examples?
Both hard and smart work improve/increase the results. Which one is better, if you only do one, depends on how much each changes the results.
If you work smarter by using Ctrl : in Excel to put today's date, that is smarter than just typing faster, but typing faster (working harder) applies to more of the work of entering data. The working smarter, there, makes too little a difference to be better.
On the other hand, if you learn how to use and maintain a sewing machine (smarter), your output will be far beyond someone who hand stitches as fast as they can (harder).
