I have written many times about how much I respect the way the San Francisco Writers Conference runs their event. The sessions are always quite diverse and the keynote addresses are always top-notch. The other thing I really enjoy is meeting and hearing from authors who have been commercially successful. There are some exceptions, but for the most part, I have found these authors to be humble and encouraging to writers.
Take for example this interview with Robert Dugoni. He is the author of a number of best-sellers, including Bodily Harm, Murder One and The Cyanide Canary. He shares how to turn rejection into motivation to be a better writer.
