Social Good

"The honor and distinction of the individual consist in this, that he among all the world's multitudes should become a source a social good."
Baha'i Writings

According to this website:

Social good = A good or service that benefits the largest number of people in the largest possible way.

I think we all understand the principle of social good, but how do we connect it to our daily lives?
