"Man has got to know his limitations"

This was the last line in the movie we just watched - Magnum Force Yes, we have watched it a few times over the years. This maybe an age thing- Kirk or I would say "I don't remember that happening". We enjoy the movie. Again. And comment on how young Clint Eastwood is.

I also think, this is the line I should be considering. There are days I really wonder why I do, what I do. It seems, all I have now are limitations. It is partly due to the lack of experience and training (most training is trial and error).

Situations arise which make me look stupid and then embarrassed, as co-workers explain in front of the customer the errors of my ways. The co-workers are not doing anything wrong. They are just being helpful in explaining the "how to" do something. I just feel their timing is off. As the customer and I exchange glances - is this going to take long?
