Hmmm, always yes persons are great to have around if you want/need your ego stroked constantly. That would get boring, where as we have the opposite extreme of the people who always will challenge you and put you on defense mode. I would think the best way to learn and gain wisdom would be "through the eyes of a child" when your heart is open and each day is a new adventure. I don't come to ATS to validate my beliefs, but to explore the minds and information of others and possibly try on something new. Ponder ..... if I may.
You said members leave behind pearls of wisdom without knowing it. Would you like to elaborate?
