Why these celebrities changed their original names?

It is believed that names determine the destiny of a person. In Kinyarwanda there is a saying, “Izina niryo muntu” which literally means “there is always a name to a person.” So why do people adopt new names or change their original names? This is word from Rwanda’s very own celebrities who have changed their names. “I chose a name that I think will keep me high in the music industry. When you are riding you keep on doing it until you reach where you want to go, so to choose the name “Riderman” I wanted to always be ahead in the music industry.”  Emery Gatsinzi, alias Riderman, Local Rwandan artist.
