You mind can’t roam free when it’s cluttered. A cluttered mind is exhausting and will trip you up and slow you down.
Maybe it’s an old to do list, a bill you need to pay, an unread book sitting on your bedside table, a tough conversation, a phone call that needs to be returned.
All this stuff clutters up your mind and sucks energy. Don’t let it fester and take up space. Get it done or let it go.
