I make it a point to retry foods I "don't like" at least once a year to confirm if I still don't like them. More often than not, that experience alone gets me to like the thing. Liking things is more fun than not liking things. Why wouldn't I want to move as many things as I can in my life from the dislike bucket to the like bucket?

To be honest, for any given thing, liking or disliking it seems pretty inconsequential. Ideally, you would like the things you can't avoid, and dislike the things you can't get. Everything else doesn't really matter too much.
