Yep, If your not willing to test yourself to the limit, how can you expect others to do the same and encourage them to do so by example?I agree, when I state my opinion I am always careful to say it is my opinion, which is not testable, I then explain why I have said opinion. I tell students that the military is not considered and great job in the nation, but I follow that up with the fact that it is dangerous, hard your mind, and hard on your body. Also, I tell them it is the best decision I ever made in my life.
