I feel bad for Monday. There’s a lot of pressure on it to be “the best time” for us to start whatever it is we want to start; a diet, an exercise regime, a novel, a regular writing practice.
Sunday is a fine day to start something new. In fact, it’s better because it’s a day earlier. It lets you get ahead of the curve.
What is it you want to start, and how will it get you closer to your goal? Go rogue; start today.
