My mental attitude about using my brain is important, because all experience and information may be important as I mature and my circumstances change. (life skills, mind, perspicacity, total recall) Mental attitude is an important characteristic of the mind (metacognition, positive, negative) which produces my person. (soul, mindset) My mental attitude should be neuroticism proof. I should not think on the basis of how I feel. Some people do avoid using their brain to make decisions. I wonder, if this is why women tend to outlive men?
