You have only one life. Your life is so very valuable not only to you, rather to everyone whom you will impact.
Stop looking at things in their micro perspective as to what is appearing today. Think about how you feeling while putting out your work into the world.
Think about the people who will be brought out of depression or sadness or hurt just because they will have a chance to meet you or see your work and change their decision of giving up.
Don’t you give up, as Bieber said. Say “let me love you” to the person in the mirror.
