I think the best thing you can do is find a way of writing in which you can express yourself best. As long as you can do this, since you are (I'm assuming) a unique person, your voice should then be unique as well (even if it's not completely original).
Originality for the sake of originality might be interesting at times, but I like it better when one knowingly chooses what elements to include in one's music, and while trying to find new expressive "heights", creates originality. Originality as the ends instead of the means is a lot more appealing to me than the other way around
