As an agent, what is your favorite lead generation technique?

[Brad Jacobson]

Hi Fellow BP Fans,

Recently I took on coaching to take my agency business to the next tier.  What I've learned is so simple that it almost seems silly to share but it's paying huge dividends right now.  The golden nugget from this coaching has been the idea of a "power hour" or simply locking myself in my office for 60 uninterrupted minutes and just getting on the phone to say "hi" to everyone in my SOI.  

What else is there that you successful agents do that produces huge dividends?  What is your favorite lead generation technique?  What is one thing you've done or learned that's help push your real estate business into the next tier?
