Fear of being useless, fear of being rejected if I'm not competent and knowledgeable.. because I'm most certainly useless when it comes to seeking acceptance/liking by virtue of my personality.
Even if I'm not unlikeable, there are so many people (the majority I'd say) that are more likeable than me, and that's all that matters when it's time to choose who gets voted off the island.
Why do you hide behind your dominant function? What are you hiding from?
I don't. When I feel the need to hide, I use Te - far more effective. I hide from suspected drains on my resources that I would prefer not to confront at the moment, or perhaps at all.
Hope is the denial of reality. It is the carrot dangled before the draft horse to keep him plodding along in a vain attempt to reach it. We should remove the carrot and walk forward with our eyes open. -- Raistlin Majere
