Yes, PD is kind of embarrassing. I even cringe at the term. I'd like to kick that Stuart Smalley "Saturday Night Live" character in the nuts
, he's really implanted a negative image in my mind about this subject. But he's pretty accurate in some superficial ways.
I prefer to think of it as being in training sort of like a Jedi (or a Sith), since they are essentially all about PD. That is marginally less dorky, i guess, but maybe not.
