"It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own self-interest. We address ourselves, not to their humanity but to their self-love, and never talk to them of our own neccessities but of their advantages."

This means that people are not going to give out money for free. You are going to have to go out and earn it. Meaning that in order for you to eat or have shelter you are going to have to obtain a job and keep it, because without this job the people who are working are not going to give out to charities.
