It can be as big as "I bought someone a new car" and as small as "I poured a glass of milk for my friend so they wouldn't have to get up". If you can't think of anything, maybe that's a sign that you should try to do something nice for someone today!
The last nice thing I've done was offered to go pick up groceries for my Mom because she's having dental work done soon and is supposed to take it easy for a few days.
