My early books may be crap, but writing them had an immense impact. Learning the dynamics of my mood enabled every success I’ve had in work and life. When I feel good, I exploit the feeling for all it’s worth. When I feel like shit, I batten down the hatches and hold on to my confidence that it will pass. That’s so important because it keeps me from changing course during a bad spell, from being tossed in the winds of my attitude. If every bad day resulted in a deconstruction of values and priorities, I’d never make headway on a worthwhile project.
