When you hear the word "productivity," you might think of getting as much done as possible in the least amount of time. Is this really the best way to work though? Grinding away at an endless list approach really the most effective way to work? I don't think it is and I don't think you do either. There's a better way, it's called being effective and I think it's worth better understanding the differences between productivity and effectiveness.
