To subdue a great problem or task, you’ll need structure. Blocking the same amount of time, every day, until the task is completed, is a good plan of approach.
This means you might need to get up at the same time every single day and establish a routine around your goal, chipping away at it until it is accomplished.
Mind you, the joy of approaching the task this way is not in its accomplishment but in the process. So, enjoy the journey!
