Psychologists discovered the dunning cruger effect, which is a cognitive bias. People with the least ability had the most confidence and vice versa. The less you know, the more confident you are. A white board where you map your projects with some really good sharpies and great postit notes can be a fantastic tool for visual management. As gray and a favorit book? I'm big fan of allan vise's million dollar consulting book. In a favourite habit, i'd like to come up some great productivity habits such as rewarding myself with coffee.
