you could be a leader in the family by doing what’s right. if you see your siblings not doing anything to help out your parents then be the better person and help them out, it’s tough being a parent who works and has kids to take care of. helping them will mean a lot and you’re siblings could see that and help out too
you could be a leader in a community by following yourself. if you see someone doing something thats wrong tell them they’re in the wrong and help them go into the right path. teach them how to do things better, and just overall be nice :)
