Old friends are great. You have been through thick and thin together and can reminisce at length about the good old days. While nostalgia can be fun, reliving great times from your youth, it can also make you feel that the best has passed. Start making new memories with all the important people in your life. Make an effort to find different shared activities and record them for posterity in photographs and mementoes so they become as vivid as your earlier experiences. Make recent experiences part of your story telling repertoire. Relive recent happy memories as well as distant ones.
