BROKER: Anyone who is paid to bring together buyers and sellers to complete a market transaction. Common examples of brokers are real estate agents, stock brokers, and insurance agents. The thing to note about brokers is that they don't buy or sell anything, but merely bring buyers and sellers together. This little function is different from that of a dealer. A dealer is one who is always ready to help a transaction by selling to those who are buying or buying from those who are selling. As such, while stock brokers are in fact brokers, matching up buyers and sellers, many are also dealers, ready to buy or sell if no one else does.

"You have to find something that you love enough to be able to take risks, jump over the hurdles and break through the brick walls that are always going to be placed in front of you. If you don't have that kind of feeling for what it is you're doing, you'll stop at the first giant hurdle. " -- George Lucas
