Early on Steve advocated the idea of simply putting a polarity to an intention, and sometimes certain intentions would just work nicely with a certain polarity. I liked this idea. But the idea of committing oneself entirely to a single polarity, it just seems so big! I understand that for some people this might be more efficient and productive, but to me, it seems that you have an intention, tack on your chosen polarity and go for it. After your intention has manifested, go yay and drop the chosen polarity and go onto your next intention.
Although, it does strike me that some intentions might only take a month or two to manifest, some might take years. Could it be the reason why Steve suggests picking a polarity and permanently sticking to it? Because of some manifestations taking so long, that it could be dangerous to drop the polarity or switch it after that certain intention has been fulfilled.
And what about people who have not heard about polarity, and yet are successfully manifesting? Are they unconsciously polarizing? Or could it be something else?
Another reason why I find committing your entire self to polarizing unappealing is that you even have to think about the really little issues, like ordering pizza. It's just pizza! It seems as if you have to expend so much thought energy thinking about you are going to react to a situation, plus it almost feels artificial trying to figure how to act out in situation in accordance to your polarity. And if I remember correctly, polarity began as a simple yet powerful aid to IM and now it has evolved to the point of becoming a new PD subject unto itself.
