Rewarding yourself for reaching your goals is a great idea, but some undertakings can take months or even years to achieve, so you risk knocking the wind out of your sails before you even get close. Instead of waiting until you've reached the big finish line to reward yourself, plan something really amazing once you've reached your halfway point (like a trip to that spa in the Bahamas), suggests Dr. Susan Bartell, a psychologist and motivational speaker. You'll be less likely to throw in the towel when things get tough around that midpoint marker.
