I would like to add one thing to your excellent list: Put your answers to questions in context.
If the question is, "Should I fly into Paris or Madrid?", your answer should not be, "Madrid is the only way to go!" if you have never accessed the Camino from both Paris and Madrid.
If the question is, "Is getting over the Pyrenees difficult?", your answer should not be, "The Pyrenees were very easy!" if you have been walking since Paris and your leg muscles are fully developed.
If the question is, "Is the snoring in albergues at night bothersome?", your answer should not be, "It never bothered me!" if you wear a hearing aid and remove it at night.
I think we owe it to each other to put our answers in context. For example, on my last Camino, I met a pilgrim who was making it clear to anyone who would listen that a particular albergue was horrible and no one should ever stay there again. I was curious as to what made it so bad, so I inquired. Was it dirty? No, it was very clean. Was it over priced? No, it was very affordable. Was there no hot water? No, it had an excellent shower room with plenty of hot water. Was the food bad? No, it was one of the best meals along the Camino. Did it have bed bugs? No, the mattress and pillow were immaculate. Was the hosptialero rude? No, he was very accommodating and funny. Was there no facility to wash clothing? No, there was a brand new washing machine and dryer. Was there no internet connection? No, it had super fast Wifi. Dumbfounded, I asked, "What made it so bad that it warranted you giving it such a bad review?" "Well," the other pilgrim replied, "The guy next to me snored all night."
