I think we discover more than change. You may think that you don't like dancing but then realize that you actually do. But if you've tried several times and don't like it you're unlikely to change. Twin studies show that twins separated at birth end up with the same interests and very similar lives. In one example twins both ended up leading the local volunteer firefighter departments in their respective towns. That's just an anecdote but the statistics show this as well, it's quite remarkable.
