If you are looking for motivational stuff you can go to Brian Tracy's site and just sign up for his email mail list and his quote of the day.
I get the quote of the day and send it out as part of my newsletter, on Twitter and to the Marketers I an training. Sometimes, one little quote can change your perspective on the day (or the job).
Personally, I am a big Napoleon Hill fan.
What kind of info were you looking for?
Also, markingriffin was right--talking to other agents who are successful is a great help. Don't be afraid to ask questions, a good agent knows there is plenty of business out there and will often give you advice. Be sure to ask about what
did not work, too. Great way to avoid repeating mistakes is to know about them ahead of time!
Good luck!
