I was once told by someone that I should end each day by crossing it off my calendar and saying out loud, "There goes another day of my life, never to return again." Try this for yourself, and notice how much it sharpens your focus. When you end a day with the feeling that you would have lived it the same if you had the chance to repeat it,you gain a sense of gratitude that helps you focus on what's really important to you.When you end the day with a feeling of regret or loss, you gain the awareness to try a different approach the next day.
