While this is true for a lot of them, it's not true for all of them. If Tim loves real estate--and it sounds like he does--perhaps he should consider teaching it and become an exception to the rule.
For example, Duncan Wierman is a refreshing exception to the rule. His teaching is solid, dependable and devoid of hyperbole. Oh he went the Dan Kennedy route to get his product out there, but once you become a member, his delivery is sober and serious--not the pixy dust delivered by most seminar junket guys.
Another exception to the rule is Mike Cantu, who had to be dragged to the podium to talk about how he achieved 38 free and clear SFRs. The title of his talk is "Don't Get Voted Off Real Estate Island." I see he has a website now; type his name dot com. As you can see, he's not yet a graduate of the Dan Kennedy School of Wild Hyperbole, Gross Exaggeration and Outright Lies.
