I think there is a time and place for both. I also think that sometimes working smarter can lead to a sloppier outcome. Say you are digging a hole. Working harder is digging it with a shovel. Working smarter is using a backhoe. You can't get the same fine detail and control with a backhoe that you can with a shovel though. I like your diagram though where you show hardwork and doing what matters coming together to create smart work.
