To Pick or Not to Pick

This question has probably been discussed on this site before I joined. I have been teaching myself to finger pick for the last year and a half and prefer to use my fingers. I've been told that I need to learn to use a pick. In my mind, the way to do it is the way that is most comfortable for the person and pleases them as they play. But I just wanted to see what other people's opinions were. If I'm happy with the way I'm playing do I need to stress myself out by trying to learn all over again with the pick? I don't have any problem using the pick when I strum.
