Managing my time is something else...akin to struggling through a never-ending jungle of brambles in the middle of a dark night, or hand-to-hand combat with an infinitely-headed hydra.
A further difficulty is that time feels amorphous to me---shape-shifting, impossible to pin down as to dimension or duration, smell, taste, or texture.
So I am trying something new. A 3-ring binder, with calendar pages, to-do lists, steps needed, notes---timetables and schedules for all projects and tasks, all in one place. Will this help? We shall see!
NOTE: I've never been good at time management. On the other hand, I've always managed to meet my publishing deadlines, and I HAVE published more than 100 books. So perhaps whether this "helps" or not is...beside the point!
