You know you cannot do everything that your mind tells you to do. So set the few up. And if your list grows longer than you intended it to be, ignore them for now.
Work on the topmost that pulls you in. That’s your innards talking to you. Do the small stuff because that sets the perspective and that’s where it all begins. The tiny things done well (imagine yourself looking back on the 366th day) would have been your best decision.
