Im not saying that Yin is worthless. I just think if somebody went all in on one or the other path the yang path followers would turn out more successful.
I can see why you'd think so, and that is reasonable.
I think yang has MORE desirable characteristics than yang but yes, introspection and creativity are both good but yang fuels the fire to really get into even those things.
So you wouldn't completely do away with Yin traits but you'd much rather Yang be your dominant form while the Yin acts as secondary aspects?
