Working Smarter Not Harder???

When I first heard the phrase, "Let's work smarter and not harder!" I really liked it.  It concisely expressed the real need for a team to think through it's actions from beginning to end before just blindly pressing forward. Recently I have altered my thinking...  I like this phrase even better... "Work smarter so that you can work harder on the things that matter!"  I get caught up in meaningless tasks that take me away from putting my time into worthy projects.  So when I get into the worthy project I am too worn out to give it the time and attention it deserves.  Nowadays I am training myself to be more attune to managing the insignificant details thus freeing up my time and energy for the more pressing and important assignments of life!  So now the big question is...How does one know the difference?  Alas...that will have to be answered in a different blog...
