It's not easy to write your own material unless you have a God-given gift. It is a lot of work: making every performance sound fresh like it is the first time you ever said any of it..is not easy...at all. As hard as it really is, it would be so worthwhile to bring smiles and laughs to a crowd of people.
I don't have a natural gift, but if someone wrote for me I'd really give performing a try. I think it would be a lot of fun.
