We're all, in our own way, good at separating what's good from what we believe to be 'not so good' in any situation. When eating a meal, we know what we like and don't like. When undertaking any task, we know what we're prepared to do willingly but are equally aware of what doesn't inspire or motivate us. In an area of your world where you feel inclined to separate likes from dislikes, relax. Allow it all to form part of a necessary picture. It is all what you need.
