Perfectionism:
I identified with a lot of the points. Fear of failure (also fear of success which is a conundrum) is a primary driver for me. and I tend much more toward procrastination than overworking which leads to tasks piling up and then to feelings of being overwhelmed. My standards and expectations of perfectionism I feel are more internally directed than externally, but they have manifested in organizing work as well (overthinking/over-planning)
