Gretchen Rubin is the best-selling author of The Happiness Project. Her latest book is Better than Before. Mastering the Habits of Our Everyday Lives.
Her thesis is that habits make change easier as they are the invisible architecture of daily life and remove the need for decision making and using self control to make changes.
But, she says, before we try to form new habits, we have to know ourselves, and know what will work, and what won't.
