Faith in one's own existence comes with self-awareness. Which comes with the snulin frailty of being. When you see people close to you go off one by one. There's nothing you can do about it. Only endure the pain of loss, again, again, again. To live on, realizing that you will never see them again. And to realize that it's your turn to come. And when you realize you're you. When you get the idea that your time is running out, day after day, which you spend just to live to see the weekend. That you're not going to be gone and you're just going to be forgotten, like you weren't there. When there is a goal to leave in this world at least something behind. And you're not particularly messed up with the design. You don't have time to stomp on your spot. The main thing is to have time, to finish, to finish. Until your last hour. Then you'll believe in your existence.
