"I'd had a long talk with Bob Silverberg, who was very influential on my early career. He'd, out of the kindness of his heart, at a convention told me that he thought I'd made several mistakes in the way I was disposing of my stories. And I said, "I don't understand what you mean, but I'll be glad to buy you a few drinks, if you'll tell me about it". So we adjourned to the bar and sat there a couple of hours. He was drinking Bloody Marys back then; I was drinking Black Russians. And he told me all sorts of things which carried me over the next several years; it was a lot of information for a couple of drinks. He told me that the first thing I should do if I wanted to write full-time was to get a really good agent. He said that after a while the business end of writing takes too much of the writing time. Better to pay someone ten percent and find that you're still more than ten percent ahead in the end. Which is true. My present agent says that he always feels that a good agent during the course of a year should earn back for his client at least the ten percent he takes by way of commission, so the client's really nothing out. And what he should ideally do is make him more money than the ten percent."
