Smart not hard

Work smart, not hard.
Last summer, I worked as a lawn care technician. One day it was raining and my boss and I decided to do maintenance of the tractors. The most time consuming and hardest part of the process was changing out the blades on the bottom of the tractor. To do this, a massive amount of torque must be applied to the screw holding the blades in place. I attempted to use only my hand strength, and while I got it done, it took much longer and was much more tiring than was necessary. My boss came over while i was working on the second tractor and showed me a much more effective method. He took a long hollow metal rod and slid it over the end of my wrench. This allowed me to have much more leverage and get the job done in half the time with half the effort. I will never forget that lesson.
