I do agree with the idea of that real world experience will always be the best teacher.

My experience on the forums is that everyone who touts a one-sized-fits-all system is (when you look at their profile) a paid teacher, coach, guru, etc.

All of the above teachers are good.

So, you could be stuck with that money tied up for the length of the wrap.If the Subject To teacher you learned that from told you this was a good idea, go get your money back.

It's also possible she's a piano teacher or a tutor, or counselor. 

It's offered to paramedics, teachers, and LEO.

It is just like a teacher in a school. 

And back to start, to be the best at what one does, takes a commitment to not 9-5 but living it, exercising, train train train, and being a leader. leaders are teachers who motivate and own others failures. 

@David Shirts, experience is the best teacher, IF YOU CAN SURVIVE!  

He is a really good teacher.
