You might live your life pretending that things aren't as they truly are; it might give you comfort to not acknowledge reality.  The rest of us prefer to grasp things for what they really are.  Pretending Trudeau is a heavyweight who will whup Trump in trade negotiations is delusional.

Having an unvarnished and realistic assessment of things is fruitful; most of us find it allows us to make decisions that result in better outcomes.  Such as in the next election.
