You nailed it with respect to analysis paralysis and intelligence….. I am often too distracted to pursue my goals due to the enormous thought that goes into planning, and then I become exhausted.
I think gender plays a role, too. Women and girls are taught to question everything about their abilities and society does a great job of reinforcing doubt.
It could be said that the current Democratic primary is an excellent example of the questioning that women endure and the double standards that still exist!
