Furthermore, how would I know what within me to focus on? If there is something troubling me, I may not be aware of it, so how would I know to diagnose myself? Well, I assume you are not psychotic so you must have some sense of introspection going on.
But I see your point, it helps to look at others situations and say, "hey, I'm kind of like that too." That's the great thing about this board. You CAN learn from other people's life experiences. It doesn't always mean you know how to diagnose the symptoms and then, effectively treat the core problem.
Some people on this board focus on the SL at the exclusion of bigger issues (hate to pick on you CeMar but your name comes to mind). He will continue to beat his head against a wall in regards to his SL in the M because he is not willing to look at other issues, mainly within himself. His posts are sporadic and evasive, can't get a good handle on what is going on there.
You tend to take an unemotional, clinical approach, while interesting and often insightful, it comes across harsh. You are obviously very intelligent but that should also include emotional intelligence. Maybe you need to work on you bedside (in this case boardside) manner
