I just finished reading a book by Jia Jiang called Rejection Proof, How I beat fear and became invincible through 100 days of rejection. The basic premise was that Jia would put himself in situations where he would get rejected and then discuss what he learned. He did crazy things like borrowing $100 from a stranger or asking the Southwest Airlines flight attendant if he could make the announcements. Each time he got rejected, he learned something and shared his knowledge.
