“Sometimes you make choices in life and sometimes choices make you.”
—Gayle Forman, If I Stay (If I Stay, #1)
In economics, they say that rational choice-making occurs at the point where marginal cost equals marginal benefit. In short, it means that as long as you have the mental capacity to think for yourself, the person whom you are today is a result of the choices you have consciously made. It means that your choices define you.
So no, don’t go about regretting your choices, because without them, there wouldn’t be you.
Be proud of your choices.
