To make a difference and be remembered you do not have to do incredible things, just being there for the people around you can save someone from a meaningless life and help them lead the life they were meant to live. Listening to other people's problems without passing judgment is one of the kindest things you can do. Also just always being kind to people, because you never know what they could be going through. Like if your at school and you see someone sitting alone, go and sit next to them because by doing that simple small act you could make their day.
