I'm a fairly freewheeling P with the a serious perfectionist streak. I've realized that a lot of my spontaneity, a lot of my ideas, have been killed by a deeply ingrained fear of failure. It's sporadic though, I can't really find a pattern to it all. A lot of times(most of the time?), I do random things that may not make sense to most people in my life, but I approach the situation with confidence and optimism. Other times though, I hesitate and sit on something for months or even years for fear that I may make some horrible, irrevocable error. But situations almost always work out as I hope, so I'm not sure where the fear of failure originates.
Any other NPs suffer from random bouts of anxiety fueled perfectionism that prevent them from acting in a way that feels authentic?
