Reminiscing about the past is a great way to learn about where you could be going in your future. So send an email off to an old friend with the subject line 'remember when' and make your correspondence take you down memory lane! Not only will it be a great way to fill your busy day with sweet energy, it will remind you about just how far you have come in your life. Marking your progress is a great way to get a focus on where you want to go next in your life.
