The Alchemist by Paulo Coelho, The Allegory of the Cave by Plato, The Odyssey by Homer, and the song March to the Sea by Twenty One Pilots all explain different aspects of following your Personal Legend, and your beliefs.
"And that no heart has ever suffered when it goes in search of its dreams, because every second of the search is a second's encounter with God and with eternity” (Coelho 134).
Plato's The Allegory of the Cave shows a similar idea by Socrates stating, "At first, when any of them is liberated and compelled suddenly to stand up and turn his neck round and walk and look towards the light, he will suffer sharp pains; the glare will distress him, and he will be unable to see the realities of which in his former state he had seen the shadows" (Plato). In comparison, the fact that when you follow your dreams in the presuit of your Personal Legend, you will have the hardships that follow. The suffering of the heart represented in The Alchemist, and the pain of getting used to reality in The Allegory of the Cave.
“And, when you want something, all the universe conspires in helping you to achieve it” (Coelho 124).
This is related to Homer's The Odyssey, (Athene:) "Hold back, men of Ithaka, from the wearisome fighting, so that most soon, and without blood, you can settle everything." This is Athena helping Odysseus on one part Personal Legend, to restore peace in Ithaca. This is showing that the universe, in a way, is conspiring to help Odysseus. (Homer XXIV)
“In order to find the treasure, you will have to follow the omens. God has prepared a path for everyone to follow. You just have to read the omens that he left for you” (Coelho 31-32)
The song March and the Sea, by Twenty One Pilots, provides a strong image of following your Personal Legend by signs .

I see a spaceship in the sky,
And hear a voice inside my head
Follow me instead"
