You read and write and sing and experience, thinking that one day these things will build the character you admire to live as. You love and lose and bleed best you can, to the extreme, hoping that one day the world will read you like the poem you want to be.
To know a species, look at its fears. To know yourself, look at your fears. Fear in itself is not important, but fear stands there and points you in the direction of things that are important. Don't be afraid of your fears, they're not there to scare you; they're there to let you know that something is worth it.
