The Success Training Network (TSTN)
I especially enjoyed the "Relationship Selling" series by Jim Cathcart. It is really in-line with our company's business approach.
Bob Proctor's "Paradigm Shift" was excellent, too!
The list of "faculty" includes Zig Ziglar, Dr. Denis Waitley, Brian Tracy, Charlie "Tremendous" Jones, Tom Hopkins, Dr. John Gray, Dr. Stephen Covey, and many, many more.
Check it out at www.tstn.com and let me know what you think!

(How do you spell the sound of a baby whining?)
Are they available in downloadable format, like a podcast?
Actually, they run it just like a TV station on the Internet. The programs are video and stream real-time. I wish you could download them like a podcast, but you can't (other than a select few that the give you when you sign up).
At first I didn't like this, but after using it a it, I got used to it and actually now enjoy it. I keep it running on a spare laptop while I'm working and I'm amazed at how much I pick up. In addition, it really helps that I hear/see the similar programs all talking about success principles in different ways.
Check out the free trial and see what you think.

But, I've found that I don't learn well by watching TV on the computer. I've proven it many times while trying to watch Breeze presentations, both live and previously recorded.
If I'm at the computer, I'll often bring up a code editor or start searching for info on the presentation. The end result is that I "lose" the presentation, am unfocused on coding and other research, and the time just sinks away unproductively.
