Pessimistic spending

People convince themselves that a purchase that benefits them in the present will have extended value in the future.

For example, buying the highest-end PC with the thought that it will outlive a lower-end PC to the point where the return in value is greater than the added financial cost.

Another example is buying an off-road vehicle for all the camping one plans to do in the future but only going a few times a year. At this point, buying a sedan and renting for those few trips would be much more economically sensible.

The perceived utility of a purchase now may or may not extend into the future.

A pessimist will spend to improve today.

An optimist will spend to improve the future.
