Efficiency is getting something done as quickly as possible.
Productivity is getting stuff done.
Too often these terms are confused. People say they want to be more productive, but what they are really saying is they want to get more done with less work.
The people I admire are people who produce. They produce good work, solid relationships, service to others. They are not worried about putting in less work. They are worried about making the biggest impact.
I want to be more productive.
