We have to be examples for our friends if they do not believe in it yet. The way i look at it is if oneself is willing to do something and have some success, hopefully those around you will want the same once they see that they can do it too.
This is why i joined Steemit myself as i am an unconventional person already. Having solar and EV for myself and benefiting from it is showing my friends that outside the norm thinking can help themselves and others around them as well.
