Convert money into memories

After the baseline Maslow-ian needs, I think the best use of money is to convert it into memories. Whether this is a great vacation, a thought-provoking film, a moving performance, or even just an interesting anecdote about the thing you bought. Even the objects you buy should be just a means to the end of obtaining memories. The bike you buy will give you memories of the rides you take, and that early-adopter consumer gadget will give you amazing stories to tell (or blog!) about how you tried and tried but just couldn't get it to work the way you wanted.
