My summer job as a teenager was taking care of plants at a nursery, which taught me the value of tangible accomplishments. Humanity craves that kind of progress, and it's often lacking in desk jobs. A senior engineer at Zapier, Fokke Zandbergen, used a combination of LEGO bricks and productivity techniques to create a system that worked for him, including color-coding his bricks to track his progress. However, when he tried to apply this system to digital tasks, it didn't work as well, leading him to build an entire LEGO set in his office, which provides a tangible sense of accomplishment and motivation.
