I will look in to it (although my life hasn't been hindered really, besides the occasional scenario mentioned in the first post). It does seem to me however, that there is a connection between what I've described and the INFP personality type:

-- "Some characteristics of NP's may include: procrastination, divergent thinking, many interests, scatter-brained, get bored easily with something that doesn't interest them, extremely focused with something that does interest them, daydream a lot... Often, these are also the descriptions of ADD behaviour." -- blog.cybette.com/archives/000089.html

-- And Paraphrasing a speed reading book I once read; "Most self-discipline manuals are written by J's and bought by P's, who will eventually find themselves slacking regardless".

While I'm not discounting ADD as a possibility, I do think that if there is a type likely to be mis-diagnosed, it would be the NP's.

curious ..synergy
I have felt that way most of my life ..sometimes id rather fade away into my toughts rather than completing a task..its gotten better though
but have you experienced anything like this ..why do you believe its add? Ive often wondered about this myself.
