However Skip, like yourself, has an ego that won't let him benefit from
his experiences, or those of others.

Now, how could you possibly know that? Especially in the case of myself who
has posted far less of my experiences here. That's where your otherwise
excellent observation that everyone makes mistakes (although it usually
*sounds* as if you and others don't) goes off the track.

Why, just the other day I learned that, if you are in very familiar waters
where navigation doesn't seem like a real issue, you can look down at your
GPS, see the asterisks you expect to be there, and turn left. Oops. The
GPS was zoomed way too far in and there was still one asterisk off the
screen. Bump. You really think I didn't learn something from that?

During my years of observing aviation human factors (where they are far more
critical), I noticed that such assumptions about others are generally
accompanied by dangerous arrogance about ones self. I don't know that that
is true about you individually but it is statistically probable. Why don't
you focus on specifics that would be useful and instructive discussion
instead of jumping to general value judgements about others that just appear
self-serving.
