The problem with time is money  In this paper, we investigate
how the impatience that results from placing a price on time
impairs individuals’ ability to derive happiness from
pleasurable experiences.   Experiment 2 revealed that a similar
manipulation decreased participants’ state of happiness after
listening to a pleasant song and that this effect was fully
mediated by the degree of impatience experienced during the
music.  Finally, Experiment 3 showed that the deleterious effect
on happiness caused by impatience was attenuated by offering
participants monetary compensation in exchange for time spent
listening to music, suggesting that a sensation of unprofitably
wasted time underlay the induced impatience.  Together these
experiments establish that thinking about time in terms of money
can influence how people experience pleasurable events by
instigating greater impatience during unpaid time.  Article
