I set out to become a comedian, and I said in order to do that the first thing I'll do is become a disc jockey and know my pop music. I like it, my voice is good, and I can start out getting confidence without an audience in front of me.
You should not look at what the person used to do, rather you should look at what kind of person they are today. The one who gets bogged down about people's pasts, is just like Iblees who said to Allaah, “You created me from fire and you created him from clay”.
