Society may have tried to train you to do things only because there was a business value or functional need; living that way can actually be very unfulfilling.
How about doing something because it may just be fun? This kind of activity makes life enjoyable.

Put on your weird clothes that you can't wear to work, grab a re-usable shopping bag, and buy something that you can't find in a chain store.
