Over the years I've been to so many seminars!
And oftentimes the techniques were amazing but there were a couple of problems.
1. I'd forget the techniques.
After being blasted with one amazing technique after another. Things would begin to blur together.
And usually a week or two later I couldn't really recall anything that was taught.
2. Off the mat experience.
Probably one of the coolest seminar experiences I ever had happened after the actual seminar was over.
A friend of mine had reserved a room at a local restaurant and bar for after the seminar.
So later that night after the seminar was over we all got together had food and drinks together. It was a great chance to talk more and hang out off the mats.
I've never had this happen at any other seminar. It's usually, "here's some techniques" and then they leave.
