I´ve always enjoyed helping people, google local guides enables me to do so, everytime I leave a review I feel that I´m helping several people, if I review a local store the owner gets important feedback and costumers gets an idea of what to expect, if I add a place to the map I´m helping other people get their bussines found and users to find what they´re looking for.
For me Local Guides Program mean connect with others and make life easier.
