You used to hate vegetables and now you order them. Taste changes. So can you.

Preferences are not fixed features of a person. Things you were certain about become untrue quietly, without a decision, just from exposure and time, and the confident statements you make about yourself at any age have a shorter shelf life than they feel like they do. What you dislike now is a current reading.

Notice where you are using an old preference as a permanent fact. Not a morning person, bad with people, not someone who reads. Test one of them again this month. Some will hold. Some have quietly expired already.
