I wonder what your corners of human mindspace were. Just to make sure that you didn't fall into some typical mind/egocentric bias trap.

Did you do any of the things in http://en.wikipedia.org/wiki/Competent_man? For example did you experience loesickness? The death of a dear one? Raise your own children? Rescue someone from a car accident? Experience major injury?
I love that list, Thanks for sharing it.

Specialization is for insects." — Robert Heinlein, Time Enough for Love So let's make a check list out of you...
