[...] Belfort explains to workers before a shift:

So you listen to me and you listen well. Are you behind on your credit card bills? Good, pick up the phone and start dialling! Is your landlord ready to evict you? Good! Pick up the phone and start dialling! Does your girlfriend think you’re a fucking worthless loser? Good! Pick up the phone and start dialling! I want you to deal with your problems by becoming rich!

This highlights the individualist subjectivity of sales, the responsibility of the worker to close the sale, and in doing so get rich and solve their own problems.
