Just watched an episode of Psych in which Spencer made a terrific comment:
Take lots of pictures. Not of sights, don’t take pictures of buildings. Take pictures of moments, because that’s what matters. Capture them in your mind and hold on to them in your heart.
Love it. Just make sure you don’t get stuck in your past and spend your days complaining on how everything was better back then. Remember Al Bundy? Seize the day, focus on the present and experience new adventures!
