Very interesting topic. I was most certainly a people pleaser through college. Still kind of coming into my own persona and identity. Once I sort of settled on a career path, that stuff sort of fell to the side. I realized I was, in fact, quite good at something and I damn well didn't need anyone else's approval to know that--I just knew.
There is a fine line between being solicitous and kind and generous on the one hand and obsequious on the other. I do think for some people, it is difficult to know how to traverse that line.
Oh, man, Fuzzy-- I try really hard not to look in the DSM5. I'm afraid I will give myself another illness!!
