Supplee's paradox

Supplee's paradox is a puzzle about the choices we make. Basically, if you have two different things that you want to do, but you can only do one, then it is not always obvious which one you should choose. For example, let's say you can either buy a toy that you really want, or you can save the money and buy a cheaper toy later. Both of these options have pros and cons. This is the kind of thinking known as Supplee's Paradox so it can be hard to know what decision to make.
