I like your lessons learned, especially 3, 5 & 6. Light all day rain does stink, I find it challenging to stay motivated in those conditions. Rain in the winter really stinks. I remember more that once being cold and wet whilst cursing mother nature as it keeps on raining. And as you said the best thing is that it will stop raining eventually, and most likely the woods will be devoid of the "less weathered" hikers.
