When I teach I explain I expect students to work hard, develop skills and increase their capacity so they can be the best they can be. I want them to be phenomenally successful. I then explain that I work hard to make them better because I am selfish because I know I can not do all the good the world needs.
I tell them if they go out and do great work and make the world a better place, I get to live in a better world. Sure they do to, but I can really only hope to make the world better for myself, family and friends and the I try to tip the scales in favor of a better world by the work I do. I hope they will work to do the same.
It is for this reason I encourage Selfish, Selfless, Synergy (video below). Nobody is all one or the other. When people are said to be selfless, they do this because they perceive this is the most important work they can do – in other words, they help others because they are selfish. As George Bernard Shaw said,
I look forward to hearing about and enjoying the good you create for everyone and everything by generating comprehensive improvements by creating interactions so everyone and everything benefits. As Kio Stark explains, talking to strangers is a way to create a better world for all of us to enjoy.
