Well, it's not easy to polarise fully, and I don't think you can get a really good idea of a polarity in thirty days! I think a thirty-day trial is better suited to a belief system or a particular style of sleeping, for instance.
I found myself cycling between polarities for a long time without actually realising that I was doing one or the other. I think it's better to study up and become conscious of what polarities you are using in your day to day life... you're on a one-lifetime trial of both polarities. If you can't see what you do in your day to day life, how can you choose?
It was pretty interesting to read your experiences, that cleared things up for me a little bit... I remember trying out the "TODAY IS MY LAST DAY ON EARTH!!" mindset for a while without getting that it was totally in conflict with my core polarity. It only made me depressed. I don't actually enjoy doing all the things people do to make their life feel meaningful when they're trying to avoid the inevitability of death!
Thanks for sharing the love
