Honestly, this is a tough industry, and a technical industry. I don't believe for one bit psychobabble like Briggs Myers applies. If you come to me I could care less what motivates you just have your technical ducks in a row and we'll be just fine. If your feelings get hurt, that's your problem not mine. People get paid a good wage in nuclear, just do your job, no one is required to compliment you or make you feel warm and fuzzy about yourself, so don't expect it. That's all one needs to succeed in nuclear.
