papa wemba was saying to jb not to listen only to those who praise him its important to listen to those who can bring criticism,and also not to listen to gossip and decide radically based on one version,also that he should not distance himself from fans he should make them feel closer to him it will help his popularity and he should also go back every now and then to the area they started from in order to make people feel he has not forgotten where he came from and make them feel "he's one of our own"
other than that he is a great musician with a lot of talent
