I believe that we all start out like guy B in the op. It definitely takes time to shed (for many of us a life time) the indoctrination of the wt. I know that i was one bitter sob when I first discovered ttatt. But as time and other rewarding facets of this real life have manifest themselves, I have gravitated to be more of guy A!
As guy A, I have come to appreciate that while life is finite, it can be filled with wonderful events and many happy days just by having a positive attitude and seeing the good in people and life!
just saying!
