So why would anyone take on this practice, especially if it's going to take a long time to learn? If you were blown away by the demonstration of "IP", then maybe you are willing to take it on faith alone. Maybe, if you're a very trusting person, taking it on some "authority's" word, maybe enough. But I have been down the "trust me" road before, and I would like to see some proof that there are results at the end of the road.
