Back in the late 90s and early 2000s I spent a lot of time reading these articles about a guy who'd travel to train martial arts all over the world. It was hosted on Geocities. I thought the site was gone forever, but because of this thread I did a search and found that it's now on its own domain. http://www.global-training-report.com/

I'm probably the only guy who is going to tell you that practice is the problem. The more you try, the more "ceiling" you'll create for yourself.

If this sounds interesting do some research on Dr J. Marvin Brown. His autobiography is available online. You might also be interested in looking up Dr Stephen Krashen.
