Special moment? Do anything you can to preserve it. Take a picture, scribble a note or steal a memento. Mark the occasion with celebration. Indulge in vice or break your own rules if you have to. Whatever it takes to help you hold onto the moment forever. Do not count on memory; it may fail you later. More likely than not, your recollection of the event will lapse from relevancy. Even the slightest trinket or scribble can help it all come back when you least expect it. Life is made up of poignant moments. It is important to revisit, track and learn from them. Nostalgia helps you recontextualize the things that are most important in life. If you collect anything, collect memories.
