The answers to your problems lie all around you. The keys to your self-discovery are waiting to be found in each sunset, each pair of eyes, each breath of fresh air. Listen to the symphony of life and you will hear yourself. Find the beauty of nature and you have found your soul.
And here's the surprising truth: As you gaze at yourself in the mirror held by another, you will see far more than your flaws. You also will see the beauty that is uniquely you; beauty that others see clearly and you may hardly know exists. That is also part of the truth about you.
Social media has infected the world with a sickening virus called vanity.
My own sense is that the acquisition of self knowledge has been made difficult by the modern world. More and more human beings live in vast urban environments, surrounded by other human beings and the creations of human beings. The natural world, the traditional source of self-awareness, is increasingly absent.
