Well I would say that, I'm a trainee teacher.
Never easy, Alexander's prose style is elaborate and often sentences will take three or four readings to really make sense. It sometimes feels as though he is being deliberately unclear... and perhaps he is. Alexander felt that his work was ill conveyed by others (he de-authorised the authorised summaries after they were written) and felt that the meaning behind his work was difficult to grasp. So he wasn't going to write an easy book from which people could walk away thinking they'd understood him, only to go on and misrepresent his work.
The bottom line is that there is NO substitute WHATSOEVER for hands on lessons. If you are reading this because you are doing a STAT course or are an existing Alexander pupil, get it. If you are reading because you are intruigued or doing a distance learning course, save your money and spend it on a lesson with a good teacher.
Oh and if you run an Alexander Technique distance learning course, have a good hard think about what you're doing, then drink some bleach.
