Bringing positive change

Life is uncertain, death is guaranteed, now I'm hoping that I could bring positive change to the people around me, especially my family. I always hope that they would live better. I can't impose anything on them. I can only pray. I know it seems like I'm thinking highly of myself when I hope people surrounding me would strive to make themselves better. I just want them to be happy, to enjoy the abundant life that God has promised each and everyone of us. I hope my life is not wasted.
