Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
Most of us have been awake and actively working for approximately 2-4 hours already. We've opened our organizers, checked our email, confirmed appointments and now, we're ready for the day. In that same planner, does is say, "worry about tomorrow?" Probably not; so don't do it. Today, stick to today's plan…that is more than enough to handle.
