" As social animals, it is imperative for us to see the actual, tangible impact of our time and effort for our work to have meaning and for us to be motivated to do it even better. The logic seems to follow Milgram’s findings, except in this case, it’s positive. When we are able to physically see the positive impact of the decisions we make or the work we do, not only do we feel that our work was worth it, but it also inspires us to work harder and do more.
