The world reminds you that there is an Ideal to everything and everyone, even in its imperfect state of existence. Of course, this includes you. You have an ideal self which you ultimately see as you, and it remains unformed and unfinished as long as you strive toward mismatched and even polar opposite goals.
But it doesn’t take the sting off much as you watch dream after dream die a mean death at the sacrificial altar of existence. The world reminds you that there are people who are living lives closer to this or that dream, even if some dreams are so at odds with each other. The world reminds you that you are privileged to dream, but not necessarily made to live out your dreams.
