While you may get reminders by email when your bills are due, don’t rely on them as the sole reminder of whom you owe money to and when. Whether you use a paper planner or the calendar on your phone, put the due date for every single bill—and the amount—on your calendar each and every month.
Don’t let yourself get lazy after a few months, thinking you’ve got all those due dates memorized. Having your bills noted on your calendar each and every month is a reminder of how much you’re spending on recurring costs month in and month out. If there’s an area that needs attention, it’ll be on your mind the minute you open your calendar.
