I essentially agree with this. When you make your own rules you understand how the system works better than anyone else on the planet, and if it is valid, you will (or should) have an extremely high level of confidence in its reliability.
It doesnt matter if the end result of your learning process is a system, skills, a healthy body, driving skills...
But if you did it your own way, if you are the engineer behind your success, it will be so much harder to take it away again from you. You will not only have results, but you will UNDERSTAND those results, and the mechanics behind them. I totally agree with you, expiated. It is a whole different level.
